Four Unknown Calculator

The 4 Unknown Calculator requires input to be in the form:
aW + bX + cY + dZ = e

Already loaded in the calculator are the 4 equations:
2W   + 3X   + 4Y     - 5Z   =   -6
6W   + 7X     - 8Y   + 9Z   =   96
10W + 11X + 12Y + 13Z = 312
14W + 15X + 16Y + 17Z = 416

Click ENTER to find the answers.
Clicking the "RESET" button will clear ALL the boxes for you.
Now, enter the equations you want to solve.
Good luck.
