Question

f=F/d-F for d

i get d=F/f+F is this correct?

Answer 1

@phi

Answer 2

if the problem is
\[ f= \frac{F}{d} - F \]
add +F to both sides
\[ f + F = \frac{F}{d} \]
divide both sides by F
\[ \frac{f+F}{F}= \frac{1}{d} \]
now "flip" both sides
\[ d= \frac{F}{f+F} \]

Answer 3

so you got it right.

Answer 4

yes

Answer 5

yep

Answer 6

if the problem is
\[ f= \frac{F}{d-F} \]
then you get something else.

Answer 7

oh wait it is like the last one

Answer 8

sorry about that

Answer 9

let me do it again and see if i'm right

Answer 10

hold on a sec...
