ok this one confuzes me 4 some reason : o
3- 2d = 7
(2d over 5)
pls explain : o
$\displaystyle \frac{3-2d}{5}=7$...now by multiplying both sides by 5 we get $\displaystyle 3-2d=35$...now by subtracting 3 from both sides you get [MATh]-2d=33[/tex]...now by dividing by -2 we get the answer $\displaystyle d=\frac{-32}{2}=-16$
