I think most graphing calculators can do this easily. My TI-89 and TI-92 can.

on my casio the simultaneous equation solver just lets you sub a, b, and c values into
anX+bnY=Cn and if you just try subbing a function such as cos into one of them it says Syn error. Does it work in a similar way on your calculator or are you able to just type in the whole equation?

When solving simultaneous equations I normally use an approach utilizing a calculator's ability to handle matrices, and the reduced row echelon form function, rref(. Can yours do that?
