Question 577196: How do I solve the following:
Adult tickets for a play cost $25 each and children's tickets cost $15 each. The total receipts were $7,200 and the total attendance was 400. How many adults and how many children attended?
I set up the system as:
25x+15y=7200
x+y=400
I then tried to substitute the second equation into the first as x=400+y, which gave me y=-175. That's where I knew I was wrong, but I don't know what else to do. And I can see this questions been asked but I'm having a very hard time following them.

x + y = 400 ___ subtracting y ___ x = 400 - y ___ minus, not plus
