Answer:

(2, 10 )

Step-by-step explanation:

Given the 2 equations

6x - y = 2 → (1)

y = 3x + 4 → (2)

Substitute y = 3x + 4 into (1)

6x - 3x - 4 = 2

3x - 4 = 2 ( add 2 to both sides )

3x = 6 ( divide both sides by 3 )

x = 2

Substitute x = 2 into (2)

y = (3 × 2) + 4 = 6 + 4 = 10

Solution is (2, 10 )
