Equations and inequations are the two types of Algebraic equations which involve solving for the unknown

variable. Inequalities contains variables and constants joined together by numerical operations and ‘greater

than >’ or ‘lesser than <’ sign. Inequalities calculator is the online tool which can solve for x given an

inequality.

Example 1: Solve the given inequality for the value of ‘x’, 3x + 4 ≥ 13.

Given inequation: 3x + 4 ≥ 13

In order to solve for ‘x’, we have to take all the numbers to the right side leaving only ‘x’ on the left side.

Subtract ‘4’ on both sides of the inequation-> 3x + 4 – 4 ≥ 13 - 4

3x ≥ 9

Divide by ‘3’ on both sides of the inequation-> 3x/3 ≥ 9/3

Hence the inequality solution is x ≥ 3

Example 2: Solve the given inequality for the value of ‘x’, 9 – 4x > -11

Given inequation: 9 – 4x > -11

In order to solve for ‘x’, we have to take all the numbers to the right side leaving only ‘x’ on the left side.

Subtract ‘9’ on both sides of the inequation-> 9 – 4x - 9 > -11 - 9

-4x > -20

Divide by ‘-4’ on both sides of the inequation-> -4x/-4>-20/-4

Whenever a negative number is multiplied or divided on both sides, then the inequality sign flips

around!

Hence the inequality solution is x < 5
