### Inequalities with Absolute Values

• To solve an inequality involving absolute value, convert the original inequality into a compound inequality that does not involve absolute value, using the definition of absolute value. For example, |2x + 3| > 4 would become: either 2x + 3 > 4 or 2x + 3 < -4.

• Describe the solution set of a compound inequality using either a number line or set builder notation.
