1. Section 2.2: Solving Absolute Value Equations

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

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

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

5. 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

6. 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

7. 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.”

8. 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
