Answer:
y = 12
Explanation:
Given the 2 equations
2x + 2 = y → (1)
2y = 5x - 1 → (2)
Substitute y = 2x + 2 into (2)
2(2x + 2) = 5x - 1
4x + 4 = 5x - 1 ( subtract 4x from both sides )
4 = x - 1 ( add 1 to both sides )
x = 5
Substitute x = 5 into (1) for corresponding value of y
y = (2 × 5) + 2 = 10 + 2 = 12
