Sorry for the thread switch, Thanks in advance!

Here are the questions:

(1) 2x - 3y = 5

(2) 4y + 2z = -6

(3) 5x + 7z = -15

Solve for X Y and Z using substitution or elimination.

EDIT :I Recently tried to use a homework help online service who gave me the answer ( I didnt understand their work though) For this they got x=4 y=1 and z=-5
