Anyway my answer is wrong :D

Answer 8

so one solution?

Answer 9

huh?

Answer 10

How did you get it?

Answer 11

guessed lol

Answer 12

Subtract equation A from B so that you can get a value for x.

Answer 13

-2

Answer 14

Nope.
\[2x+y-(x+y)=4-2\]
\[2x+y-x-y=2\]
\[x=2\]

Answer 15

ohhh... so its one solution?

Answer 16

For y you just substitute the value for x.

Answer 17

Yeah :)
