    m = (-13) / 20

    Step-by-step explanation:

    Solve for m:

    6 (3 m + 1) = - 2 m - 8 - 4 + 5

    Grouping like terms, - 2 m - 8 - 4 + 5 = - 2 m + (-8 + 5 - 4):

    6 (3 m + 1) = - 2 m + (-8 + 5 - 4)

    -8 + 5 - 4 = - 7:

    6 (3 m + 1) = - 7 - 2 m

    Expand out terms of the left hand side:

    18 m + 6 = - 2 m - 7

    Add 2 m to both sides:

    18 m + 2 m + 6 = (2 m - 2 m) - 7

    2 m - 2 m = 0:

    18 m + 2 m + 6 = - 7

    18 m + 2 m = 20 m:

    20 m + 6 = - 7

    Subtract 6 from both sides:

    20 m + (6 - 6) = - 6 - 7

    6 - 6 = 0:

    20 m = - 6 - 7

    -6 - 7 = - 13:

    20 m = - 13

    Divide both sides of 20 m = - 13 by 20:

    (20 m) / 20 = (-13) / 20

    20/20 = 1:

    Answer: m = (-13) / 20
