Answer:

(8, 11 )

Explanation:

Given the 2 equations

2x + 2y = 38 → (1)

y = x + 3 → (2)

Substitute y = x + 3 into (1)

2x + 2(x + 3) = 38 ← distribute and simplify left side

2x + 2x + 6 = 38

4x + 6 = 38 ( subtract 6 from both sides )

4x = 32 ( divide both sides by 4 )

x = 8

Substitute x = 8 into (2) for corresponding value of y

y = 8 + 3 = 11

Solution is (8, 11 )
