Example: A question like solve through comparison

4x + 2y = -2

2x - 3y = 1

I got (0,1) but is there a way I can plug those two equations up there into my calculator just to see what the final answer is? I still need to work it out and whatever but it would greatly reduce the risk of making simple mistakes... well it would show me that I *did* make a mistake..
