If you don't even know what one of the variables are, you can't solve the equasion. There IS no solution.

First 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
