    O god here we go again lol

    [LaTeX ERROR: Convert failed] ....subtracting 5 from both sides you get[tex]\frac{-2}{7d}=-2[/MATh]...now by divding by a negative you get[tex]\frac{2}{7d}=2[/MATh] multiplying by 7d you get 2=14d...and then by dividing by 14 you get d=1/7

    OK then

    ok follow my work until we get to the \frac{2}{7d}=2...and rewrite it as \frac{2d}{7}=2 now multiply both sides by \frac{7}{2} to get d=7
