So for this, I will be doing the elimination method. Firstly, multiply both sides of the first equation by 2:

Next, add the two equations together to get
. From here you can solve for x.
For this equation, just divide both sides by 8 and your first answer will be 
Now that we have the value of x, substitute it into either equation to solve for y:

<u>In short, the solution is (2,-5), or A.</u>
