  1. Solve each system. Homework Help ✎

    1. x + 2y + z = −1
      4xyz = −1
      −3y = 2z

Eliminate the denominators by
multiplying before trying to solve.

2x + y = 16

2x − 3y = −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.
