Exactly 512 tickets were sold for the talent show at Cypress Middle School. The number of student tickets sold was three times the number of adult tickets sold. How many adult tickets were sold? Write the system of equations:

128 adult tickets were sold.

Step-by-step explanation:

We can form an equation using the information we have, let x be the number of adult tickets sold:

3x + x = 512

4x = 512

x = 128

x is the number of adult tickets sold as the number of student tickets was three times more so the 3x was the student tickets.

So 128 adult tickets were sold.

384 student tickets and 128 adult tickets

Step-by-step explanation:

S for student and A for adult

s+a=512

s=3a

3a+a=512

4a=512

a=128

s=384
