    Step-by-step explanation:

    9x + 3y + 12 = 0

    add - 3y to both sides.

    add - 12 to both sides.

    divide both sides by 9.

    Answer: x=-1/3 y + - 4/3

    18x + 6y + 24 = 0

    add - 6y to both sides.

    add - 24 to both sides.

    divide both sides by 18.

    Answer: x=-1/3 y+-4/3
