how did you get that?
(2,3) is not a solution.
ok thanx
6(2)-3(3)=3 (not 6)
Your guess was correct in an ordered pair, the x is first, y second.

Yes
4x-2y=-4 is this a solution? -1=x and 0=y

There are many more solutions, and that was one of them.
Just plug in the x value and y value and see if it works.
5x+y = -15 (2,-5) it equals positive 15 right?
5(2)+(-5)=10-5=5 That is not a solution it results in 5, not a -15. Don't forget the y value was a -5 (2,-5)
