Step-by-step explanation:
x+z = 1, z = 0
x + 0=1
x = 1
3x+3z= 3
3(1) + 3(0) = 3
3 = 3
Let s be the number of student tickets and a be the number of adult tickets.
s + a = 85; a = 85 - s
Also,
5s + 10a = 600
Substituting a from the first equation
5s + 10(85 - s) = 600
-5s = -250
s = 50
a = 85 - 50 = 35
The school sold 50 student tickets and 35 adult tickets.
