    Answer:

    y = 3/4

    Step-by-step explanation:

    Given two equations

    -3x+2y = 7 … (1)

    -3x-2y = 4 … (2)

    Subtracting the second equation from the first will give us;

    -3x-(-3x)-2y-(+2y) = 4-7

    -3x+3x-2y-2y = -3

    -2y-2y = -3

    -4y = -3

    y = 3/4

    The result of the difference between the second and the first will give y = 3/4
