Question

[02.03]

Solve for x: -3|x + 7| = -12

x = 5 over 3, x = −19 over 3

x = −3, x = −11

x = −3, x = 11

No solution

Answer 1

x=-3, x=-11

Answer 2

to solve for x: -3|x + 7| = -12 first divide by -3 on both sides so
|x + 7| = 4 which separates out into
x + 7 = 4 and -(x+7)=4 now solve for x
-7 -7 -x - 7 = 4
x = 4 - 7 x = -4 -7
