    We are given that y = 3 - 2x

    We will substitute with this value in the second equation as follows:

    -6y + 18 = 12x

    -6 (3-2x) + 18 = 12x

    -18 + 12x + 18 = 12x

    This will give us zero = zero

    A 0=0 solution means that the system has infinitely many solutions.

    Therefore, the answer is (c)
