a)         y + 4x = 14

To find the cost of the shoe rental (represented as y), we plug in the number of games and isolate the y:

y + 4x = 14                        We plug in 3 for x because they bowled 3 games:
y + 4(3) = 14                      Then, multiply:
y + 12 = 14                        Subtract 12 on each side to isolate the y:
y = 2

b)           So, the cost of shoe rentals is $2.
