    m = - 7

    Step-by-step explanation:

    1/9 (2m - 16) = 1/3 (2m + 4)

    (2m - 16) = 9/3 (2m + 4)

    2m - 16 = 3 (2m + 4)

    2m - 16 = 6m + 12

    4m = - 28

    m = - 7

    m = -7

    Step-by-step explanation:

    1/9 (2m - 16) = 1/3 (2m + 4)

    Multiply each side by 9 to get rid of the fractions

    9*1/9 (2m - 16) = 9 * 1/3 (2m + 4)

    2m-16 = 3 (2m+4)

    Distribute

    2m-16 = 6m + 12

    Subtract 2m from each side

    2m-16 - 2m = 6m-2m + 12

    -16 = 4m + 12

    Subtract 12 from each side

    -16-12 = 4m+12-12

    -28 = 4m

    Divide each side by 4

    -28/4 = 4m/4

    -7 = m
