7-157.

Solve this system of equations: $5x − 4y − 6z = −19\\−2x + 2y + z = 5 \\3x − 6y − 5z = −16$

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.
