Answer:

x = 11, y = 13

Step-by-step explanation:

Given the 2 equations

y = x + 2 → (1)

5x - 4y = 3 → (2)

Substitute y = x + 2 into (2)

5x - 4(x + 2) = 3 ← distribute and simplify left side

5x - 4x - 8 = 3

x - 8 = 3 ( add 8 to both sides )

x = 11

Substitute x = 11 into (1) for corresponding value of y

y = 11 + 2 = 13
