<u>Answer:</u>
B) Multiply the second equation by −3 to get −3x − 12y = −48
<u>Step-by-step explanation:</u>
We are given two equations:
--- (i)
--- (ii)
If we multiply the second equation by -3, we get:

--- (iii)
Combining equation (i) and (iii) to get:

3x and -3x cancel each other so x is eliminated and we are left with:

Therefore, the correct answer option is B) Multiply the second equation by −3 to get −3x − 12y = −48.
