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.

Equation 1)  
a= b= c= d= e=

Equation 2)  
a= b= c= d= e=

Equation 3)
  a= b= c= d= e=

Equation 4)
  a= b= c= d= e=

  W=   X=
  Y=   Z=

This calculator (as well as the 2 unknown and 3 unknown calculator)
finds the solutions by evaluating determinants using Cramer's rule.
