Answer:

(11, 2 )

Step-by-step explanation:

3y + 2x = 28 → (1)

x = 5y + 1 → (2)

substitute x = 5y + 1 into (1)

3y + 2(5y + 1) = 28 ← distribute parenthesis on left side and simplify

3y + 10y + 2 = 28

13y + 2 = 28 ( subtract 2 from both sides )

13y = 26 ( divide both sides by 13 )

y = 2

substitute y = 2 into (2)

x = 5(2) + 1 = 10 + 1 = 11

solution is (11, 2 )
