Please help!! 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 third equation.
2x - 3y + z = -4
2x - 2y + z = -1
x - 2y + 3z = -6

replace \(x\) everwhere you see it in the top two equations by \(2y-3z-6\)

ok for the first i got y-5z=8

first one would simplify to \(2y-5z=8\)
