    Answer:

      infinite number of solutions

    Step-by-step explanation:

    The two equations describe the same line.

    Adding 9y+15 to the second equation makes it be …

      15 = 6x +9y

    Dividing that by 3 gives you …

      5 = 2x +3y . . . . . . identical to the first equation

    The lines intersect at every point, so there are an infinite number of solutions.
