    x=0

    y=6

    Step-by-step explanation:

    3y - 12x = 18

    2y-8x = 12

    rearrange the equation

    2y-8x=12

    add 8x to both sides

    2y=8x+12

    divide both sides by 2

    y=4x+6

    now substitute it into 3y-12x=18

    3 (4x+6) - 12x=18

    simplify

    12x+18-12x=18

    simplify

    18=18

    x=0

    substitute to find y

    2y-8 (0) = 12

    2y=12

    y=6

    Recheck:

    3 (6) - 12 (0) = 18

    18=18

    2 (6) - 8 (0) = 12

    12=12
