    Algebra

    I am stuck on this problem.
    -[-|-3|(-2-m)-4] = -2[(-3-m)-2m]

    I am an old duffer trying to learn some math.
    Any help would be appreciated.
    The answer is supposed to be -8/9
    Thanks,
    Jerry

    You have to work from the inside out on the parentesis then brackets
    I started off with the absolute value sign and the steps are as follows:

    -[-(3)(-2-m)-4]=-2[-3-3m] Absolute value of -3 and subtract -2m
    -[6+3m-4]=6+6m Distribute -3 through and distribute -2 through
    -[2+3m]=6+6m Add like terms together
    -2-3m=6+6m Distribute the negative through the equation
    -8=9m Put like terms on each side of the equation
    -8/9=m Divide -8 by 9 to get your result

    Hope this helps you!!

    -[-|-3|(-2-m)-4]=-2[(-3-m)-2m]

    -[-3(-2-m)-4]=-2[-3-m-2m]

    -[6+3m-4]=-2[-3-3m]

    -[2+3m]=6+6m

    -2-3m=6+6m

    -8=9m

    m=-\frac{8}{9}
