This is the Powerpoint lesson I use to teach Solving Absolute Value Equations. My textbook has absolute value equations and inequalities lumped together in their chapter on inequalitites. I separate the two topics teaching solving absolute value equations in the Solving Equations (Ch 2) chapter, and Solving Absolute Value Inequalities
in the chapter for Inequalities (Ch 3).
