Question

Solve for x: −3|2x + 6| = −12

Answer 1

x = 1 and x = 5
x = −1 and x = −5
x = −9 and x = 3
No solution

Those are the answers.

Answer 2

What have you done so far?

Answer 3

The first step is to isolate the absolute value expression.

Answer 4

1. divide each side by -3, to get the abs(2x+6)=4
Now you let 4 be positive and negative.

the new two equations are:
2x+6=4 and 2x+6=-4

Now solve for x which is -1 and -5.
