Ok, I have this math sheep due tomorrow and I completely forgot how to do this simple problem that I used to wiz through just a few months ago.

How do you do these:

{2x-3y=1
{-x+4y=2

But imagine the { thingees are actually one big { thingee spanning the height of both equations.

Solve one equation in terms of x. x= (something). Then put that back into the other remaining equation. This will give you an anwser for y first. Then you can use either equation and your now known y value to find the x value.

OOOOOOh, now I remember, Thank you so much :)
