Question

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.

Answer 1

You're on the right track. After you get both equations you need to cancel one of the variables. In this situation, it doesn't matter which variable you cancel out.
