There are two solutions to an
absolute value equation. How To Solve Absolute Value Equations 1. Remember you are looking for two solutions. You must get rid of the absolute value symbol before you can find the solutions. Each solution comes from a different equation. We will refer to these equations as case 1 and case 2. example: ê3x + 2 ê= 4
