I don't understand how to figure this out. Couldn't you have multiple answers?
The total receipts for a basketball game are $1,400 for 788 tickets. Adults paid $2.50 and students paid $1.25. The tickets takers count only the amount of tickets, not the type of tickets sold. Determine the number of each type of ticket sold.

let the number of adult tickets sold be x
then the number of student tickets is 788x
2.5x + 1.25(788x) = 1400
solve for x
