13-50.

Solve each system. Homework Help ✎

*x*+ 2*y*+*z*= −1

4*x*−*y*−*z*= −1

−3*y*= 2*z*

Eliminate the denominators by

multiplying before trying to solve.

2*x* + *y* = 16

2*x* − 3*y* = −16

(4, 8)

Solve the last equation for *z* in terms of *y*,

then substitute into the other two equations

to find *x* and *y*. Use those values to find *z*.
