how do i solve this?!?!

4x-2y=32
-3x-5y=-11
Answered by bobpursley
I would multiply the top equation by 5, and the bottom equation by 2

20x-10y=160
-6x-10y=-22
then subtract the bottom equation (remember to change the signs)

26x=182 solve for x.

alright i got x=7 but now what do i do?
Answered by bobpursley
Go back to either of the original equations, put in 7 for x, and solve for y.
Answered by mike
so for example

4(7)-2y=32 or -3(7)-5y=-11

and then it equals 28-2y=32 or

-21-5y=-11
then what from their this is driving me insane!
Answered by bobpursley
add 21 to each side.

divide each side by -5

I think the answer is y=2,but you better check.
Answered by bobpursley
Yep, 2 is almost right, but not quite. Check to see why.
