Question 953276
I have only figured out the first equation of this problem I am having trouble setting up the second equation, could someone help me? I'm preparing for a test and I'm having trouble: 
Five hot dogs and three hamburgers cost a total of $6.20. Two hot dogs cost .50 cents more than a hamburger. How much does each hot dog and each hamburger cost? 
First equation I found: 5x+3y=6.20 
***
let d=cost of each hot dog
let h=cost of each hamburger
..
5d+3h=6.20
2d=h+.50
h=2d-.50
5d+3(2d-.50)=6.20
5d+6d-1.50=6.20
11d=6.20+1.50
11d=7.70
d=.70
h=2d-.50=1.40-.50=.90
cost of each hot dog=$.70
cost of each hamburger=$.90
