Question

Plz Help, i really dont understand this, and I'm taking a timed test!

Solve for x: −3|x + 7| = −12 (2 points)

A. x = 5 over 3 , x = − 19 over 3
B. x = −3, x = −11
C. x = −3, x = 11

Answer 1

B. x = −3, x = −11

Explanation:

−3|x + 7| = −12

-3x - 21 = -12 and -3x - 21 = 12

-3x - 21 = -12

-3x = 9

x = -3

-3x - 21 = 12

-3x = 33

x = -11
