A small business inventory coordinator is analyzing storage constraints modeled by the following system of linear equations:

{x+2y+6z=5−x+y−2z=3x−4y−2z=1\left\{\begin{array}{l} x + 2y + 6z = 5 -x + y - 2z = 3 x - 4y - 2z = 1 \end{array}\right.

To solve this system using the elimination method, the coordinator adds the first and second equations together to yield 3y+4z=8{}3y + 4z = 8, and adds the second and third equations together to yield −3y−4z=4-3y - 4z = 4. Adding these two intermediate equations together eliminates al
