Question

Identify a possible first step using the elimination method to solve the system and then find the solution to the system.

12x – 3y = 6
2x – y = 2
A) Multiply second equation by 6, solution (2, 0).
B) Multiply second equation by 6, solution (-2, 0).
C) Multiply second equation by -6, solution (0, 2).
D) Multiply second equation by -6, solution (0, -2).

Answer 1

D

Explanation:

Answer 2

D

Explanation:

You have to multiply it by -6 since you are trying to get ride of the x so make the x value line up and negative to cancel out.

If you plug in (0,-2) then it will work so it is the solution

12(0) - 3(-2) = 6

0 + 6 = 6

6 = 6
