Solving a System of Linear Equations

The program below will solve a system of two linear equations written in the

form Ax  By  C and Dx  Ey  F.

Name = SLVSYSTM

:Disp “FIRST X-COEFFICIENT”

Displays the quoted message.

:Input A Accepts a value for A.

:Input F

:If AE  BD  0

If the determinant of the coefficients is zero,

:Goto 1 the program will go to “Lbl 1.”

:(CE  BF)/(AE  BD) → X Value is calculated and stored for X.

:Disp X

:(AF  CD)/(AE  BD) → Y

Value is calculated and stored for Y.

:Disp Y

:Goto 2

Program will go to “Lbl 2.”
