      Absolute Value Inequalities. Solving absolute value inequalities combine the strategies you used in: 1) Solving and Graphing Compound Inequalities 2) Solving Absolute Value Equations. Every absolute value inequality is a compound inequality. The 2 separate inequalities come from when you split the inequality once the absolute value is isolated.
