2. Absolute Value Review
 |5| =
 |-5| =
 |x| = 5

3. Absolute Value Equations
 Have two answers!
 To solve |ax + b| = c
 Write: ax + b = c or ax + b = -c
 Solve both equations
 Check your answers!

4. Examples
 |x – 4| = 6
 |3x + 1| = -5

5. Examples
 |3x| = 5

6. You Try!
 |x| = 10
 |3 + x| = -3
 |4x – 5| = 8

7. Multi-Step Abs. Value Equations
 Get | | part alone first.
 Then write and solve two equations.
 Example:
 |3x + 9| - 10 = -4

8. Example
 -2|5x – 1| - 3 = -11

9. You Try!
 |x + 2| + 5 = 9
 4|2x + 7| = 16
