Input equations in this form:
aW + bX + cY + dZ = e

These 4 equations are already input:
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 of the boxes for you.
Now, enter the equations you want to solve.
Good luck.
