–x + y = 0

Answer 1

A.


x = 10; y = –3


B.


x = –1; y = –1


C.
x = 14; y = 5


D.
x = 22; y = 7

Answer 2

What do you think it is? I can tell what the solution is just by looking at the second equation.

Answer 3

>.> Your that good eh?

Answer 4

Its B

Answer 5

yep.

Answer 6

lol I took the hint from what you said

Answer 7

Multiplied the bottom by 3

Answer 8

Thanks

Answer 9

-x + y = 0
you can tell that the number have to be the same.
(-1,-1) = -(-1) - 1 = 0
same thing goes for (1,1), (2,2) and so on.

Answer 10

Again you shouldn't use my method, unless you actually know how to solve through the methods of elimination and substitution which you used, so good job.
