3x-4y=25
-5y=20
y=-20/5
y=-4
3x+y=5
3x+(-4)=5
3x=5+4
3x=9
x=3

Answer:
Step-by-step explanation:
It usually works well to let a variable represent quantity of the highest-value contributor. Here, that is the quantity of adult tickets.
Let "a" represent the number of adult tickets sold. Then (324-a) is the number of admission fees for children. The total revenue is ...
5.40a +2.50(324 -a) = 1390
2.90a +810 = 1390 . . . . eliminate parentheses
2.90a = 580 . . . . . . . . . subtract 810
a = 200 . . . . . . . . . . . . . .divide by 2.90
The number of children admitted was 124; the number of adults admitted was 200.
