## Answers ( No )

First we write the variables:

x: cost of the ticket for adults.

y: cost of ticket for children.

We write the system of equations:

2x + 3y = 31

2x + 2y = 26

We solve the system:

Step 1:

2x + 3y = 31

-2x-2y = -26

Step 2:

y = 5

Step 3:

2x + 3y = 31

2x = -3y + 31

x = (- 3y + 31) / 2

x = (- 3 * (5) +31) / 2

x = 8

Answer:the prices for an adult and child movie ticket are:adults = $ 8children = 5 $
