Answer:

r = 10

y = 11

Explanation:

4y = 40 + 4

4(r + 1) = 40 + 4

4(r) + 4(1) = 40 + 4

4r + 4 = 40 + 4

4r + 4 = 44

4r + 4 - 4 = 44 - 4

4r = 40

4r ÷ 4 = 40 ÷ 4

r = 10

-----------------------------------------

y = r + 1

y = (10) + 1

y = 11

-----------------------------------------

4y = 40 + 4

4(11) = 40 + 4

4(11) = 44

44 = 44
