Y = x + 5....so we sub in x + 5 for y in the other equation

4x + y = 20
4x + x + 5 = 20
5x + 5 = 20
5x = 20 - 5
5x = 15
x = 15/5
x = 3

y = x + 5
y = 3 + 5
y = 8

solution is (3,8)

Answer: 4 games

Step-by-step explanation:

Whether Denise bowls or not, he incurs rent for bowling shoes and per bowling he has to pay $4.75 while he rented shoes for $3.

Then the equation is:

y = 3 + 4.75x

Where

y is the total cost

x is Number of bowling

y = 3 + 4.75x

3 + 4.75x = 22

4.75x = 22 - 3

4.75x = 19

x = 19/4.75

x = 4

Denise bowled 4 games.
