    y=12 x=4

    Step-by-step explanation:

    I will be using the elimination method to solve this

    *2 y = 3x

    *3 y = 2x-4.

    2y = 6x

    - 3y = 6x-12

    -1y = - 12. y = 3x

    /-1 / -1. 12 = 3x

    y=12. / 3 / 3

    4=x

    x = - 4

    y = - 12

    Step-by-step explanation:

    Since y is 3x,

    3x = 2x - 4

    On solving we get x as - 4

    Substitute x and we get y as - 12
