Math Help - Solving Linear equations

1. Solving Linear equations

ok this one confuzes me 4 some reason : o

3- 2d = 7
(2d over 5)

pls explain : o

2. OK heres what you do follow my steps

$\frac{3-2d}{5}=7$...now by multiplying both sides by 5 we get $3-2d=35$...now by subtracting 3 from both sides you get [MATh]-2d=33[/tex]...now by dividing by -2 we get the answer $d=\frac{-32}{2}=-16$
