Will mark ! find the solution of this system of equations 4x-5y=-52 -4x+3y=44

Solve the following system:{4 x - 5 y = -52 | (equation 1){3 y - 4 x = 44 | (equation 2)
Add equation 1 to equation 2:{4 x - 5 y = -52 | (equation 1){0 x - 2 y = -8 | (equation 2)
Divide equation 2 by -2:{4 x - 5 y = -52 | (equation 1){0 x+y = 4 | (equation 2)
Add 5 × (equation 2) to equation 1:{4 x+0 y = -32 | (equation 1){0 x+y = 4 | (equation 2)
Divide equation 1 by 4:{x+0 y = -8 | (equation 1){0 x+y = 4 | (equation 2)
Collect results:  {x = -8                  {y = 4
Please note the { are supposed to span over both equations but it interfaces doeans allow it. See attachemtn for clarification.

The volume is 56.8 triangular the
