Answer 2

Wow, lots of work to solve...

Answer 3

I know :(

Answer 4

Well, since I taught you how to solve these... lets guess and check. Ill try C and D, you try A and B.

Answer 5

Am I solving for X or Y

Answer 6

C, gave me 0=-5 when I plugged in y.

It gave you y=2x-5, so plug in the answer choice as the answer in the second equation then substitute the y in and solve for x.

Answer 7

D, gave me -10=10

Answer 8

The answer is B, because it ends up giving -5=-5 for infinite solutions.

Answer 9

Yeah thats what I got, thank you. I got a couple more is that ok?

Answer 10

Ok.
