Central middle school sold 50 tickets for one night at the school play. Student tickets sold for 2$ each and adult tickets sold for 3$ each. They took in 135$. How many of each type of ticket did they sell?

X = Student tickets sold.
Y = Adult tickets sold.
Eq1: x + y = 50 Tickets.
Eq2: 2x + 3y = $135.
Multiply Eq1 by 2 and add the Eqs:
2x  2y = 100
2x + 3y = 135
Sum: Y = 35
In Eq1, replace Y with 35:
x + 35 = 50
X = 15
