a family of 7 bought tickets to the circus. Each family member also bought a souvenir that cost $6. The total amount they spend was $147. how much did one ticket cost?

x = 15

Step-by-step explanation:

y = family members = 7

x = cost of ticket

7x + 6y = 147

Substitute 7 for y:

7x + 6 (7) = 147

7x + 42 = 147

Subtract 42 on both sides:

7x + 42 = 147

- 42 - 42

7x = 105

Divide both sides by 7:

7x = 105

x = 15
