lets say (x , 4) is the ordered pair that is a solution to x - 3y = 3

in this case y = 4 and we need to find x

plug y = 4 into x - 3y = 3

x - 3*4 = 3

x = 3 + 3*4

x = 15

The first ordered pair is (15 , 4)

lets say (6 , y) is the ordered pair that is a solution to x - 3y = 3

in this case x = 6 and we need to find y

plug x = 6 into x - 3y = 3

6 - 3*y= 3

3y = 6 - 3

y = 3/3

y = 1

The second ordered pair is (6 , 1).
