Question

Solve for x.

1 + |2 + x| =9

A. x = 4 or x = -8
B. x = 7 or x = −11
C. x = 5 or x = -9
D. x = 6 or x = -10

Answer 1

D. x = 6 or x = -10

Explanation:

First, you have to isolate x. We can start by subtracting 1 on both sides.

`|2 +x| = 8`

Take the opposite of the absolute value of 8 (-8 and 8)

Subtract two from both sides...

x = -10 and 6
