**Jen**, Saturday, August 28, 2010 at 11:09pm3x-2y-4=-6

3x-2y=-2*

4x+4-y=7

4x-y=3*

So your 2 new equations are

3x-2y=-2

4x-y=3

Multiply the bottom equation by -2 to cancel the y's gives us

-8x+2y=-6

3x-2y=-2

-5x=-4

x=4/5

Plug the x value into either of your "2 new equations above" to figure out y.
