Answer: 250 adult tickets band 186 student tickets were sold.
Step-by-step explanation:
Let x represent the number of adult tickets that were sold.
Let y represent the number of student tickets that were sold.
A total of 436 tickets were sold for the school play. They were either adult tickets or student tickets. It means that
x + y = 436- - - - - - - - -1
There were 64 fewer student tickets sold than adult tickets. It means that
x = y + 64
Substituting x = y + 64 into equation 1, it becomes
y + 64 + y = 436
2y + 64 = 436
2y = 436 - 64 = 372
y = 372/2
y = 186
x = y + 64 = 186 + 64
x = 250
