If you were to use the substitution method to solve the following system, choose the new system of equations that would result if x was isolated in the second equation.
3x – 5y + z = 12
x + 6y – z = –4
2x – 5y – 2z = –8
A) 4x + y = 8
–17y = 0
B) 2x – 11y = 16
4x + 7y = –16
C) –23y + 4z = 24
–17y = 0
D) 13y – 2z = 24
7y – 4z = 0
