Answer:

infinitely many

Step-by-step explanation:

I an going to solve these by elimination.  Multiply the first equation by 3

3(x-2y) = 3*6

3x - 6y = 18

This first equation multiplied by 3 is exactly the same as the second equation.  This means they are the same line.  If they are the same line, they have infinitely many solutions.
