Sometimes we need to solve Inequalities like these:
Our aim is to have x (or whatever the variable is) on its own on the left of the inequality sign:
We call that "solved".
Example: x + 2 > 12
Subtract 2 from both sides:
x + 2 − 2 > 12 − 2
x > 10
How to Solve
Solving inequalities is very like solving equations , we do most of the same things ...
... but we must also pay attention to the direction of the inequality .
Some things can change the direction !
< becomes >
> becomes <
≤ becomes ≥
≥ becomes ≤
Safe Things To Do
These things do not affect the direction of the inequality:
- Add (or subtract) a number from both sides
- Multiply (or divide) both sides by a positive number
- Simplify a side
Example: 3x < 7+3
We can simplify 7+3 without affecting the inequality:
But these things do change the direction of the inequality ("<" becomes ">" for example):
- Multiply (or divide) both sides by a negative number
- Swapping left and right hand sides
Example: 2y+7 < 12
When we swap the left and right hand sides, we must also change the direction of the inequality :
12 > 2y+7
Here are the details:
Adding or Subtracting a Value
We can often solve inequalities by adding (or subtracting) a number from both sides (just as in Introduction to Algebra ), like this:
Example: x + 3 < 7
If we subtract 3 from both sides, we get:
x + 3 − 3 < 7 − 3
And that is our solution: x < 4
In other words, x can be any value less than 4.
What did we do?
And that works well for adding and subtracting , because if we add (or subtract) the same amount from both sides, it does not affect the inequality
Example: Alex has more coins than Billy. If both Alex and Billy get three more coins each, Alex will still have more coins than Billy.
What If I Solve It, But "x" Is On The Right?
No matter, just swap sides, but reverse the sign so it still "points at" the correct value!
Example: 12 < x + 5
If we subtract 5 from both sides, we get:
12 − 5 < x + 5 − 5
That is a solution!
But it is normal to put "x" on the left hand side ...
... so let us flip sides (and the inequality sign!):
Do you see how the inequality sign still "points at" the smaller value (7) ?
And that is our solution: x > 7
Note: "x" can be on the right, but people usually like to see it on the left hand side.
Multiplying or Dividing by a Value
Another thing we do is multiply or divide both sides by a value (just as in Algebra - Multiplying ).
But we need to be a bit more careful (as you will see).
Everything is fine if we want to multiply or divide by a positive number :
Example: 3y < 15
If we divide both sides by 3 we get:
3y /3 < 15 /3
And that is our solution: y < 5
Well, just look at the number line!
For example, from 3 to 7 is an increase , but from −3 to −7 is a decrease.
See how the inequality sign reverses (from < to >) ?
Let us try an example:
Example: −2y < −8
Let us divide both sides by −2 ... and reverse the inequality !
−2y < −8
−2y /−2 > −8 /−2
And that is the correct solution: y > 4
(Note that I reversed the inequality on the same line I divided by the negative number.)
So, just remember:
When multiplying or dividing by a negative number, reverse the inequality
Multiplying or Dividing by Variables
Here is another (tricky!) example:
Example: bx < 3b
It seems easy just to divide both sides by b , which gives us:
... but wait ... if b is negative we need to reverse the inequality like this:
But we don't know if b is positive or negative, so we can't answer this one !
To help you understand, imagine replacing b with 1 or −1 in the example of bx < 3b :
- if b is 1 , then the answer is x < 3
- but if b is −1 , then we are solving −x < −3 , and the answer is x > 3
The answer could be x < 3 or x > 3 and we can't choose because we don't know b .
Do not try dividing by a variable to solve an inequality (unless you know the variable is always positive, or always negative).
A Bigger Example
Example: x−3 2 < −5.
First, let us clear out the "/2" by multiplying both sides by 2.
Because we are multiplying by a positive number, the inequalities will not change.
x−3 2 ×2 < −5 ×2
x−3 < −10
Now add 3 to both sides:
x−3 + 3 < −10 + 3
And that is our solution: x < −7

Graph Inequalities on the Number Line
What number would make the inequality x > 3 x > 3 true? Are you thinking, “ x could be four”? That’s correct, but x could be 6, too, or 37, or even 3.001. Any number greater than three is a solution to the inequality x > 3 . x > 3 .
We show all the solutions to the inequality x > 3 x > 3 on the number line by shading in all the numbers to the right of three, to show that all numbers greater than three are solutions. Because the number three itself is not a solution, we put an open parenthesis at three.
We can also represent inequalities using interval notation . There is no upper end to the solution to this inequality. In interval notation, we express x > 3 x > 3 as ( 3 , ∞ ) . ( 3 , ∞ ) . The symbol ∞ ∞ is read as “ infinity .” It is not an actual number.
Figure 2.2 shows both the number line and the interval notation.
We use the left parenthesis symbol, (, to show that the endpoint of the inequality is not included. The left bracket symbol, [, shows that the endpoint is included.
The inequality x ≤ 1 x ≤ 1 means all numbers less than or equal to one. Here we need to show that one is a solution, too. We do that by putting a bracket at x = 1 . x = 1 . We then shade in all the numbers to the left of one, to show that all numbers less than one are solutions. See Figure 2.3 .
There is no lower end to those numbers. We write x ≤ 1 x ≤ 1 in interval notation as ( − ∞ , 1 ] . ( − ∞ , 1 ] . The symbol − ∞ − ∞ is read as “negative infinity.” Figure 2.3 shows both the number line and interval notation.
Inequalities, Number Lines, and Interval Notation
The notation for inequalities on a number line and in interval notation use the same symbols to express the endpoints of intervals.

We can represent all the numbers between two and five with the inequality 2 < x < 5 . 2 < x < 5 . We can show 2 < x < 5 2 < x < 5 on the number line by shading all the numbers between two and five. Again, we use the parentheses to show the numbers two and five are not included. See Figure 2.4 .

Solve Linear Inequalities
A linear inequality is much like a linear equation—but the equal sign is replaced with an inequality sign. A linear inequality is an inequality in one variable that can be written in one of the forms, a x + b < c , a x + b < c , a x + b ≤ c , a x + b ≤ c , a x + b > c , a x + b > c , or a x + b ≥ c . a x + b ≥ c .
A linear inequality is an inequality in one variable that can be written in one of the following forms where a , b , and c are real numbers and a ≠ 0 a ≠ 0 :
When we solved linear equations, we were able to use the properties of equality to add, subtract, multiply, or divide both sides and still keep the equality. Similar properties hold true for inequalities.
We can add or subtract the same quantity from both sides of an inequality and still keep the inequality. For example:
Notice that the inequality sign stayed the same.
This leads us to the Addition and Subtraction Properties of Inequality.
Addition and Subtraction Property of Inequality
For any numbers a , b , and c, if a < b , then a < b , then
For any numbers a , b , and c, if a > b , then a > b , then
We can add or subtract the same quantity from both sides of an inequality and still keep the inequality.
What happens to an inequality when we divide or multiply both sides by a constant?
Let’s first multiply and divide both sides by a positive number.
The inequality signs stayed the same.
Does the inequality stay the same when we divide or multiply by a negative number?
Notice that when we filled in the inequality signs, the inequality signs reversed their direction.
When we divide or multiply an inequality by a positive number, the inequality sign stays the same. When we divide or multiply an inequality by a negative number, the inequality sign reverses.
This gives us the Multiplication and Division Property of Inequality.
Multiplication and Division Property of Inequality
For any numbers a , b , and c ,
When we divide or multiply an inequality by a :
- positive number, the inequality stays the same.
- negative number, the inequality reverses.
Sometimes when solving an inequality, as in the next example, the variable ends upon the right. We can rewrite the inequality in reverse to get the variable to the left.
Think about it as “If Xander is taller than Andy, then Andy is shorter than Xander.”
Solve each inequality. Graph the solution on the number line, and write the solution in interval notation.

Most inequalities will take more than one step to solve. We follow the same steps we used in the general strategy for solving linear equations, but make sure to pay close attention when we multiply or divide to isolate the variable.

When solving inequalities, it is usually easiest to collect the variables on the side where the coefficient of the variable is largest. This eliminates negative coefficients and so we don’t have to multiply or divide by a negative—which means we don’t have to remember to reverse the inequality sign.

Just like some equations are identities and some are contradictions, inequalities may be identities or contradictions, too. We recognize these forms when we are left with only constants as we solve the inequality. If the result is a true statement, we have an identity. If the result is a false statement, we have a contradiction.

Solve Applications with Linear Inequalities
Many real-life situations require us to solve inequalities. The method we will use to solve applications with linear inequalities is very much like the one we used when we solved applications with equations.
We will read the problem and make sure all the words are understood. Next, we will identify what we are looking for and assign a variable to represent it. We will restate the problem in one sentence to make it easy to translate into an inequality. Then, we will solve the inequality.
Sometimes an application requires the solution to be a whole number, but the algebraic solution to the inequality is not a whole number. In that case, we must round the algebraic solution to a whole number. The context of the application will determine whether we round up or down.

Solving Inequalities Worksheets
Inequalities in mathematics demonstrate a relationship between two values when these two values are unequal. These value s can be numbers or algebraic expressions. When practicing with solving inequalities worksheets, students are presented with an engaging and fun way to learn inequalities and solve problems at their own pace. Solving inequalities worksheets can guide students through graphical representations using real-life examples and relatable situations. ...Read More Read Less
The Benefits of Solving Inequalities Worksheets:
Analyze boundaries :
For situations where exact equality is not achieved, inequalities can help students assess boundary values of the required result. Even though students do not get the precise result, they can identify upper or lower boundaries.
Flexibility in prediction :
This leaves room for flexibility for scenarios where changes might occur, therefore lowering the possibility of error that may have been generated from the prediction of a fixed outcome.
Real world application :
Solving inequalities worksheets can show students how these boundaries and predictions can be implemented in our daily lives through mathematical solving of linear inequalities.

While solving simple inequalities or linear inequalities in mathematics, there are four possible results for the comparison of the left-hand side (LHS) to the right-hand side (RHS) of an inequality sign:
- Less than (<): LHS is always lesser in value than RHS
- Less than or equal to ( ? ): LHS is lesser or equal in value to RHS
- Greater than (>): LHS is always greater in value than RHS
- Greater than or equal to ( ? ): LHS is greater or equal in value to RHS
Students are provided with real-life examples and can learn to solve inequalities through these worksheets.
Ravi was asked to buy a maximum of 80 chocolates. These chocolates are sold in packets, each of which contains 12 chocolates. Find the number of packets he needs to buy to satisfy the requirement.
Assume that Ravi has to buy x number of packets to meet the requirements. Each packet contains 12 chocolates.
Thus we can write the above problem in the form of linear inequality as:
12 * number of packets < 80
12x < 80
=> 12x/12 < 80/12 (Dividing both sides with 12)
=> x < 20/3
Therefore the number of packets Ravi needs to buy to meet the requirement is 20/3.
Or, x < 6.66 (as 20/3 is equal to 6.66)
Because the number of packets cannot be in a fraction, we must round it up to 6 packets.
This is how a scenario can be represented in the form of inequalities.
Inequalities can be solved by either of the following methods:
- Addition or subtraction of the same number from both sides of the inequality sign without altering the sign
- Multiplication or division of the same non-zero positive number to both sides of the sign. In the case of multiplication or division with a negative number, the inequality sign will be reversed.
Printable Solving inequalities Worksheets
Solving inequalities worksheets can be downloaded or printed so students can practice with them at their own pace and convenience. The printable worksheets contain varying levels of difficulty, from simple inequalities to more complex ones, to assist students in understanding this concept.
What are the solving inequalities worksheets about?
Solving inequalities worksheets are free printable fun and interactive worksheets that contain questions based on inequalities. The worksheets have real-life questions that will help students in connecting inequality with real-life situations.
What is inequality?
Inequality is the representation of two algebraic expressions which are not equal. We use “<” or “>” signs to represent inequality. Students can find good practice questions in the solving inequalities worksheets.
How is inequality differ from equations?
The equation is used to represent two algebraic expressions when the are equal but inequality is used to represent two algebraic expressions when the are not equal. For equations we use “=” sign but for inequality we use “<” or “>”.
What are the methods used in solving inequalities worksheets to solve questions?

Solving Inequalities Worksheets
Inequalities come in as a new territory to explore since so far we have always tried to get an answer. In contrary to the general notion of getting one answer, solving inequalities might end up at getting one, more, or no answers at all. Multiple answers mostly come as a range but it should not come as a surprise as all those values hold true for the given inequality.
Benefits of Worksheet on Solving Inequalities
When you are doing worksheets on solving inequalities, you become fluent with the process. In order to solve an inequality, you need to perform a certain number of arithmetic operations and in the beginning, it might appear as cumbersome. Solving a few questions would make it easier for you to face and solve the question when it actually comes in front of you. It will help you get an edge over the rest of the students.

Mahesh Makhija, Technology Consulting Leader, EY India , said, “As an organization deeply committed to pioneering tech-driven innovations and solutions, we are excited about the transformative potential of Gen AI.
