Sep 17, 2014 · Unit #2.Lesson #1.Equations and Their Solutions In this lesson we make sure that students understand the basic concept of what a solution to an equation is in terms of truth values. This is emphasized up front, as opposed to bringing in checks at the end. To solve an equation containing an absolute value, you want to isolate the absolute value expression. Once that is done, you can rewrite the absolute value equation as two equations, where one of the statements equates the value within the absolute value to the positive quantity on the other side of the equation and one that equates the value with the absolute value to the negative (or ...
