Option D: Multiply the second equation by 4 and then add the result to the first equation is the correct answer.

Step-by-step explanation:

Given that:

x-4y = 2

2x+y = 12

For elimination, one of the variable is eliminated.

In this system,

we can either multiplying the first equation by 2 or second equation by 4.

Then we can add the equations.

By multiplying the second equation with 4 and then adding both equations, we can eliminate the variable y.

4(2x+y=12)

8x+4y=48

By adding

(x-4y)+(8x+4y)=2+48

7x=48

Hence,

Option D: Multiply the second equation by 4 and then add the result to the first equation is the correct answer.
