Equation form: aX + bY + cZ = d
Equation 1) a= b= c= d=
Equation 2) a= b= c= d=
Equation 3) a= b= c= d=
X= Y= Z=
Equations are entered in this form: aX + bY + cZ = d
Example, when you want to find the three unkowns x y and z:
2X + 3Y + 4Z = 119
5X - 6Y + 7Z = 80
8X + 9Y + 10Z = 353
The result is X=12 Y=13 Z=14
