Which of these steps will eliminate a variable in this system? 6x-3y=8 and 2x+6y=16

The answer is A.

Step-by-step explanation:

6x - 3y = 8

2x + 6y = 16

We can multiply the second by 3 and subtract the first from the second, or the second from the first, to eliminate the x.  (A works).

We can multiply the first by 2 and add the two together, to eliminate the y.  (None of the steps work).
