Equations are entered in this manner:
      aX + bY + cZ = d

EXAMPLE: For the equations:
      2X   + 3Y     + 4Z = 119
      5X   - 6Y     + 7Z =   80
      8X  + 9Y   + 10Z = 353

You would enter:
Equation 1) 2  3  4 119
Equation 2) 5 -6  7  80
Equation 3) 8  9 10 353

Click E N T E R for the answers:
          X=12    Y=13    Z=14


Equation 1) a= b= c= d=

Equation 2) a= b= c= d=
