The most efficient way to solve this problem is isolating the y in the first equation because:
6x + 3y = 27
3y = 27 - 6x
y = 9 - 2x
Since all the numbers have a common factor of 3, it can be easily simplified/reduce.
If you used any other variable, you would have gotten a fraction.
Now that you found y, you can substitute it into the other equation to solve for x.
ANYWAYS, your answer is A
