Given:
63 tickets were sold.
Money collected = $742.
Evening tickets cost $14 each.
Matinee tickets cost $10 each.
Let
x = number of evening tickets sold
y = number of matinee tickets sold
Then
x + y = 63 (1)
14x + 10y = 742 (2)
From (1), obtain
y = 63 - x (3)
Substitute (3) into (2).
14x + 10(63 - x) = 742
4x + 630 = 742
4x = 112
x = 28
y = 63 - 28 = 35
Answer: 28 evening and 35 matinee tickets were sold.
