Ответ:
33 adult tickets and 21 student tickets
Step-by-step explanation:
We will create a system of equations.
Let x = the number of adult tickets sold and let y = the number of student tickets sold
x + y = 54
3x + 2y = 141
We can cancel out the y by multiplying the first equation by -2.
-2x - 2y = -108
3x + 2y = 141
Adding these equations together we get:
x = 33
Plugging this into the equation, we have:
38 + y = 54
y = 21
There were 33 adult tickets and 21 student tickets
