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

Answer 1

x = -1 and x = -5

Explanation:

Part 1

−3|2x + 6| = −12

1. divide -3 by -3 and -12 by -3

|2x + 6| = 4

2. subtract 6 from 6 and 6 from 4

2x = -2

3. divide 2x by 2 and -2 by 2

answer: -1

Part 2

−3|2x + 6| = 12

1. divide -3 by -3 and 12 by -3

|2x + 6| = -4

2. subtract 6 from 6 and 6 from -4

2x = -10

3. divide 2x by 2 and -10 by 2

answer: -5

hope this helps!
