Hece, option B is correct.
Step-by-step explanation:
Given the system of equations

Multiply x − 3y = 6 by 2: 2x-6y=12

so




so the system of equations becomes

Solve 8y = -8 for y

Divide both sides by 8





subtract 6 from both sides


Divide both sides by 2


Therefore, the solution to the system of equations be:

Hence, option B is correct.
