7-157.

Solve this system of equations: Homework Help ✎ 5*x* − 4*y* − 6*z* = −19

−2*x* + 2*y* + *z* = 5

3*x* − 6*y* − 5*z* = −16

Use elimination to eliminate *y* from equations 1 and 2.

Use elimination to eliminate *y* from equations 2 and 3.

Use your two new equations to solve for *x* and *z*. Don't forget to solve for *y* as well.
