7-163.

Solve this system of equations: Homework Help ✎

5

*x*− 4y − 6*z*= −19

−2*x*+ 2y +*z*= 5

3*x*− 6y − 5*z*= −16

Use the Elimination Method to eliminate *y* from the first and second equations.

Use the Elimination Method to eliminate *y* from the second and third equations.

Use the two new equations you have formed to solve for *x* and *z*. Remember to solve for *y* as well.
