Solve the following equation

|2x+6|-7=40

|2x+6|-7 = 40

|2x + 6| - 7 + 7 = 40 + 7

|2x + 6| = 47

Absolute Value Equations

Since this is an absolute value equation

Setup two equations

- 2x+6 = 47
- 2x+6 = -47

2x+6 - 6= 47 - 6

2x = 41

Keep our =

Solution to absolute value equation 1 is

**x = 20.5**

2x+6 - 6= -47 - 6

2x = - 53

Keep our =

Solution to absolute value equation 2 is

**x = -26.5**
