Find an ordered pair (x, y) that is a solution to the equation.
x-3y=9

Answer:
(12,1)
Step-by-step explanation:
Infinite combinations can work here, but basically this question is asking to find a number that subtracted by 3 times the value of something equal 9. Those two values formed into an ordered pair, (x,y), will be the answer.
In this case, 12 being x can be subtracted by 3 and 1 (y value) and they equal nine.
