Answer :
You are given only one equation, but are to find the values of two variables (x and y). No soap.
However, you could arbitrarily let x=1 and then find the corresponding y value.
Then 3(1) + y = 9, so y = 6. One point on this line is (1,6). But there are an infinite number of other solutions.
