The total revenue that is obtained from selling the tickets is the sum of the revenue from selling the child tickets and the adult tickets. If x and y are the number of child and adult ticket, the equation that would represent the given is,
4x + 6y = 420
The equation that would allow us to solve for the number of adult tickets is,
6y = 420 - 4x
Simplifying,
<em>y = 70 - 2x/3</em>
