Two Linear Equations Using Cramer's Rule - Program for TI-83 calculator

Hello everyone,

Here we present a program to solve the system:
Ax + By = C, Dx + Ey = F

Program for TI-83 calculator By Jonathan L. Moscovici

Using material from Weisstein, Eric W. "Cramer's Rule." From MathWorld--A Wolfram Web Resource. http://mathworld.wolfram.com/CramersRule.html

Input “A:“ , A
Input “B:“ , B
Input “C:“ , C
Input “D:“ , D
Input “E:“ , E
Input “F:“ , F

( ( (BF)-(CE) ) / ( (BD)-(AE) ) ) → X
( ( (CD)-(AF) ) / ( (BD)-(AE) ) ) → Y
