I’m not sure this is right or not but, I think the answer is A

Answer:

D

Step-by-step explanation:

Given the 2 equations

2x + y = 8 → (1)

x - 3y = - 3 → (2)

Multiplying (2) by - 2 and adding to (1) will eliminate the x- term

- 2x + 6y = 6 → (3)

Add (1) and (3) term by term

(2x - 2x) + (y + 6y) = (8 + 6), that is

7y = 14 ( divide both sides by 7 )

y = 2 → D
