The answer is d. complementary angles are always angles that add up to 90 degrees. so, you can eliminate answer A and C. the question mentions a fraction which is 1/3 so u can assume the answer should have a fraction aswell. That eliminates answer B so you're left with C

There are many ways to solve this. I think the easiest way for this one is to add the equations up.

$\: \: \: \: \: -5x+ 2y = 6 \\ + \: \: \: 10x - 2y = - 16 \\ - - - - - - - - - - \\ \: \: \: \: \: \: 5x = - 10$
The you solve that, now that y is gone. You get x=2.

Now plug in x into one of the original equations.

$- 5(2) + 2y = 6 \\ - 10 + 2y = 6$
Finish solving, and you get y=8.

The answer is (2,8)
