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

We already have an equation for x, so plug it into the second equation to find the value of y, then plug that into the z equation & solveee |dw:1337613581890:dw|
