Question

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

I think it is C. x = -3, x = 11

Answer 2

Divide both sides by -3, then find x+7=4, and x+7=-4
X+7=4 x+7=-4
x+7-7=4-7 x+7-7=-4-7
x=-3 x=-11

B. x=-3, x=-11

Answer 3

Really you

Answer 4

:P

Answer 5

ok hopefully i can trust this answer

Answer 6

@whovianchick

Answer 7

Haha yes you can

−3|x + 7| = −12
−3|x + 7|/-3 = −12/-3
|x + 7| = 4

X+7=4 x+7=-4
x+7-7=4-7 x+7-7=-4-7
x=-3 x=-11

B. x=-3, x=-1

There's all the work

Answer 8

And, plug both the answers in. They work. Aaaaaaaalways plug the solutions in to check for extraneous solutions.

Answer 9

x=-3 or x=-11

Answer 10

100%

Answer 11
