At a concession stand, three hotdogs and two hamburgers cost 8.50, two hotdogs and three hamburgers cost 9.00. What is the cost

of one hamburger and one hotdog?
So far I have:
x=hotdog
y-hamburger
3x+2y=8.50
2x+3y=9.00
For the life of me I cannot remember any of the steps past that. Any help would be awesome.
