Section 2.2: Solving Absolute Value Equations

Objective: By following instructions, students will be able to: Solve an absolute value equation.

explain 1A Solve the absolute value equation algebraically. Graph the solutions on a number line. |3x|+2=8

explain 1B Solve the absolute value equation algebraically. Graph the solutions on a number line. 3|4x-5|-2=19

Your-Turn #1 Solve each absolute value equation algebraically. Graph the solutions on a number line. ½ |x+2|=10 -2|3x-6|+5=1

explain 2A Isolate the absolute value expression in each equation to determine if the equation can be solved. If so, finish the solution. If not, write “no solution.” -5|x+1|+2=12

explain 2B Isolate the absolute value expression in each equation to determine if the equation can be solved. If so, finish the solution. If not, write “no solution.”

Your-Turn #2 Isolate the absolute value expression in each equation to determine if the equation can be solved. If so, finish the solution. If not, write “no solution.” 3 |½ x+5|+7=5

Revisit Objective: Did we... Solve an absolute value equation?
