Follow the systematic procedure to solve absolute value inequalities. Different examples provided in each step for better understanding of procedures involved. Take me directly to solved examples. Arrange the inequalities such that the absolute value expression stays to the left and the coefficient always 1. Now the coefficient of absolute value expression becomes 1. Important note: When you multiply or divide wtih negative numbers, inequality reversed.

When two inequalities are joined by the word and , the solution of the compound inequality occurs when both inequalities are true at the same time. It is the overlap, or intersection, of the solutions for each inequality. When the two inequalities are joined by the word or , the solution of the compound inequality occurs when either of the inequalities is true. The solution is the combination, or union, of the two individual solutions. In this section we will learn how to solve compound inequalities that are joined with the words AND and OR.
Equations and inequalities are both mathematical sentences formed by relating two expressions to each other. When you substitute the variable in an open sentence with a number the resulting statement is either true or false. If the statement is true the number is a solution to the equation or inequality.
