    m=8

    Step-by-step explanation:

    -88=-3 (4m+5) - (1-3m)

    -88=-12m-15 - (1-3m) < - Distributive Property

    -88=-12m-15-1+3m < - Open () if there is a negative negative the symbol equals positive

    -88=-9m-16 < - Simplify

    0=-9m+72 < - Add 88 to both sides

    9m = 72 < - Add 9m to both sides

    9m = 72

    /9 / 9

    m=8
