What’s the answer ? use the picture to see the problem

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.

Ijust need these 2 questions answered (the second pic is just confirmation i'm not confident in that answer)
