The answer is #1, #6, and #8.
First, let's solve for x.
2/3(6x + 12) = -24
4x + 8 = -24
4x = -32
x = -8.
Answer #1 is correct because that equation was one of the steps in our problem. Also, #6 and #8 is correct using the same logic. Therefore, we can cross out #2, #3, and #4, since #3 and #4 have the same answer which is wrong.
