Homework Help: algebra 1

Posted by kyle on Tuesday, December 5, 2006 at 10:23pm.

I'm stuck on this problem. Can you help?
-4x-9y=1
-x + 2y =-4 WHat is x and y?

Two equations in two unknowns. Here is a quick way to solve them
-4x - 9y = 1
4x - 8y = 16
(I got that my multiplying both side so the secind equation that you provided by -4)
Now add the two equations:
-17y = 17
y = -1
Use that and any of the first equations to solve for x.
