Solve for y.
Add -3x to both sides to get rid of the 3x on the left





Multiply both sides by 







Make up any value for , say  and substitute:

 



So one ordered pair (x,y) is (1,-5)

Make up another value for , say  and substitute:

 



So a second ordered pair (x,y) is (3,1)

Make up one more value for , say  and substitute:

 



So a third ordered pair (x,y) is (4,4).
