your 3rd equation is incorrect
general admission is $15
The box office sold 360 tickets to a concert at
the college. The total receipts were $4,170. General
admission tickets cost $15 and student tickets cost $10.
How many of each kind of ticket was sold?
This is what I was doing
x+y=360
x=360-y
10(x)+8(y)=4170?
plugged in 10(360 - y)+8y=4170
Should I have 3600-10y if distribute right?

okay. I just realized that. I was doing this late at night and completely missed it. But I got the right solution now.
10(360-y)+15=4170.
-10y+15y+3600=4170. Simply the variable...
..5y+3600=4170. Subtract 3600 from both sides..
Divide the answer by 5.. You should have (y=114)?
