**Veronica**, Wednesday, January 6, 2010 at 6:18pmFirst you multiply the first equation by 5 and the second equation by -2.

You get:

10x+25 = 80

-10x+4y = -22

You cancel out the 10x. Therefore you add the two equations and you get

29y=58

y=2

You plug in 2 for y in any one of the original equations and you get:

x= 3
