Ch 6.7 Objective: To solve inequalities involving absolute value.

Steps for Solving 1.Replace the absolute value symbol | | with parenthesis. 2.Outside of the parenthesis place a plus or minus sign ± (creating two inequalities – one with a plus sign & one with a minus sign). 3.Solve for BOTH inequalities. Remember to distribute the negative.
