x=1
x=2
x=3

2(1)-y=4
2-y=4
-2 both sides
-y=2
÷-1 both sides
y=-2

(1,-2)


2(2)-y=4
4-y=4
-4 both sides
-y=0
y=0

(2,0)


2(3)-y=4
6-y=4
-6 both sides
-y=-2
÷-1 both sides
y=2

(3,2)

If you replace x with, for instance -1,1, and 3, you get (-1,-6), (1,-2), and (3,2) as solutions of the equation 2x-y=4
