Section 13.3: Solving Absolute Value Equations

Objective(s): 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. a) b)

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

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

Isolate the absolute value expression in the equation to determine if the equation can be solved. If so, finish the solution. If not, write “no solution.” Your-Turn# 2 a) b)

Revisit Objective(s): Did we... solve an absolute value equation?
