Answer 3

You could also try a simple substitution since you have a lonely x in the second equation. Just remember to get rid of the negative.

Answer 4

I would do elimination because 5 and -5 are already opposites.. so x=2

Answer 5

Now plug the x into one of the equations

Answer 6

-(2)+5y=18
5y=20
y=4
Sooo....
(2,4)

Answer 7
