represents the values of which variable in the solution of the equations below?
2x- y + z = -2
x +2y + 6z = 3
3x -y + 2z=-1
a) x
b) y
c) z
d) none of the variables Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! None of the variables. You would be solving for Z if
the numerator matrix and the denominator matrices were
switched.
