1. Solving Absolute Value Equations

2. Absolute Value equations have two possible solutions
What could x be?
Solution x=8 or -8
Absolute Value equations have two possible solutions

3. Isolate the absolute value bars on one side
Then drop the bars and set up the problem twice
once set equal to the + option
once set equal to the - option

4. Ex. 1:
Case 1
Case 2 or
x=7 or -3

5. Plug in answer to Check:

6. Ex. 2: Isolate the absolute value bars first
Then drop the bars and set up the problem twice for + / - options
Work continued 

7. Case 1
Case 2 or

8. Isolate the absolute value bars first
Ex. 3:
Isolate the absolute value bars first
Work continued 

9. Then drop the bars and set up the problem twice for + / - options
Ex. 3:
Then drop the bars and set up the problem twice for + / - options or
