Answer:
500 adult tickets
Step-by-step explanation:
Let adult and student tickets be x and y.
The number equation is
x + y = 980
The value equation is
5x + 2y = 3460
Let's multiply the first by two and subtract it from the second...
5x + 2y = 3460
-(2x + 2y = 1960)
and we get
3x = 1500
x = 500 adult tickets
y = 480 student tickets
