Inequality is an expression in algebra that has the symbols  <, >, >=, <=

y \geq 3x - 5

 y + 5 < 2x – 7

The inequalities can be plotted on a graph paper as you would a normal equation of the form ax+by+c=0.

Operations such as addition, subtraction, multiplication and division can be performed on inequalities as you would on normal equations. The same rules apply.

The same number can be added on both sides of the inequality so that the original value does not change. This rule is applicable to subtraction, multiplication and division also.
