Answer:

Infinite solutions.

Step-by-step explanation:

3x-y = 3

9x-3y = 9

multiply the first equation by -3 so as to eliminate y:

-9x + 3y = -9

Adding this to the second equation, we get:

0 + 0 = 0

This means that there are infinite solutions to this pair of equations ( they are basically the same equation).

If you graphed these 2 equations they will give you the same straight line, and the roots are all the points on that infinite straight line.
