Answer:

see explanation

Step-by-step explanation:

Given the 2 equations

- 6x - 4y = 2 → (1)

- 4x - 7y = 2 → (2)

Multiplying (1) by 4 and (2) by - 6 will eliminate the x- term

- 24x - 16y = 8 → (3)

24x + 42y = - 12 → (4)

Add (3) and (4) term by term

26y = - 4 ( divide both sides by  26 )

y = \frac{-4}{26} = - \frac{2}{13}
