Answer:

Both 6

Step-by-step explanation:

Hi there,

Adult tickets = 'x'

Child's ticket = 'y'

8x + 2y = 60......(1)

2x + 3y = 30......(2)

Multiply (1) by 3 and

(2) by 2

24x + 6y = 180....(1)

4x + 6y = 60......(2)

Subtract (2) from (1)

 

20x = 120

x = 6

Substitute x = 6 into (2)

2x + 3y = 30

2(6) + 3y = 30

12 + 3y = 30

3y = 30 - 12

3y = 18

y = 6

Adult's ticket = $6

Child's ticket = $6

Hope this helps :-)
