    infinitely many solutions

    Step-by-step explanation:

    I assume that you meant

    3x = - 12y + 15 and x + 4y = 5 (you accidentally omitted the 'y')

    Multiplying the second equation by 3 yields

    3x + 12y = 15

    ... which is identical to the first equation. Thus, the two lines coincide, and we conclude that there are infinitely many solutions.
