    y = 141/44

    Step-by-step explanation:

    Solve for y:

    (-47) / 4 = (-11 y) / 3

    (-47) / 4 = (-11 y) / 3 is equivalent to (-11 y) / 3 = (-47) / 4:

    (-11 y) / 3 = - 47/4

    Multiply both sides of (-11 y) / 3 = (-47) / 4 by - 3/11:

    (-3 (-11) y) / (11*3) = (-3) / 11 * (-47) / 4

    (-3) / 11 * (-11) / 3 = (-3 (-11)) / (11*3):

    (-3 (-11)) / (11*3) y = (-3) / 11 * (-47) / 4

    (-3) / 11 * (-47) / 4 = (-3 (-47)) / (11*4):

    (-3 (-11) y) / (11*3) = (-3 (-47)) / (11*4)

    (-11) / 11 = (11 (-1)) / 11 = - 1:

    (-3-1 y) / 3 = (-3 (-47)) / (11*4)

    (-3) / 3 = (3 (-1)) / 3 = - 1:

    --1 y = (-3 (-47)) / (11*4)

    (-1) ^2 = 1:

    y = (-3 (-47)) / (11*4)

    11*4 = 44:

    y = (-3 (-47)) / 44

    -3 (-47) = 141:

    Answer: y = 141/44
