First move the 15 over:
9-15=-2x
-6=-2x
Now divide:
3=x

A,B,C,or D

texaschic101 · Answer

9 = -2x + 15
9 - 15 = - 2x
-6 = - 2x
3 = x
check...
9 = - 2x + 15
9 = -2(3) + 15
9 = -6 + 15
9 = 9 (correct)
Are you sure you wrote the equation correctly, or are your answer choices written correctly. Because the answer is 3

e.cociuba · Answer

how so?

texaschic101 · Answer

you think it is B.....lets check..
9 = - 2x + 15
9 = -2(-12) + 15
9 = 24 + 15
9 = 39 (I don't think so)
