Question

Use a transformation to solve the equation. –3d = –27 A. d = –30 B. d = –24 C. d = –9 D. d = 9

Answer 1

when you divide both sides by three you get d=9

Answer 2

the answer is d 9 because -3d you divide it by itself and it cancels out and the you do the same to the other side and a negative and a negative give you a positive so it's 9
