Overview

This equations solves for X and Y in the system of equations:
AX + BY = C
DX + EY = F

This equation uses the Let and Get functions. Solve for X and Y. There is no solution if the matrxi [[A B][D E]] is singular.##
Listing

SIM2X2:0*(A+B+C+D+E+F+L(M:A*E-B*D))=
IF(S(X):(C*E-B*F)÷G(M)-X:IF(S(Y):(A*F-C*D)÷G(M)-Y:0)
