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

We break this into two different equations:

-3(x + 7) = -12

and

-3(x - 7) = -12

------------------------

-3(x + 7) = -12

Distribute -3 into the parenthesis:

-3x - 21 = -12

Add 21 to both sides:

-3x = 9

Divide -3 to both sides:

x = -3

------------------------

-3(x - 7) = -12

Distribute -3 into the parenthesis:

-3x + 21 = -12

Subtract 21 to both sides:

-3x = -33

Divide -3 to both sides:

x = -11

thank u 10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 times!!

Answer 3

This is wrong the answers are right!!
Subtract 21 to both sides:

-3x = -33

x = -11
