Question

(x-y=1)
(2x+y=8)

Answer 1

this is using a graph with it any help would be much appreciated

Answer 2

The way i was taught was to start with a T chart separating the x and y. After that you write a couple of random number in the x place and then solve for y my plugging the x in the equation.. After you plug the line in a graph, you do the same thing with the other equation and end up with two lines intersecting a one point...make sense??
