If the equations contradict each other, then you have no solutions. If the equations are equivalent to each other, you have infinite solutions. If the equations are distinct, you will get precisely one solution.

Notice however, that if you multiply the second equation by a factor of 3, you get the same equation as the first equation.

Since they are equivalent to each other, you will have infinite solutions.
