What is the solution of the system? Use substitution.
x = –2y + 10
–6y = 6x – 6
z = –3x + 10y
A. x = 9, y = –8, z = 114
B. x = –8, y = 9, z = 114
C. x = –8, y = 114, z = 9
D. x = 114, y = 9, z = –8

Best ResponseYou've already chosen the best response.0You distribute 6 into brackets \[–6y = 6( –2y + 10 ) – 6\] \[6y=12y+606\] Add 12y to both sides, 6y=54 Divide both sides by 6 y=9
