Absolute Value Inequalities Steps: 1.Get absolute value alone 2.Write two inequalities 3.Solve for the variable 4.Graph the solution set and write in proper form #1: Page 3 First inequality looks like original without absolute value symbol! Second inequality, you switch the inequality and negate the side opposite the absolute value symbol. Also, drop the absolute value symbol. Now graph solution: on number line. Determine: 1.Open or closed circles 2.Direction of line
