Question

f=F/d-F for d

how do i do this cause i got it wrong

Answer 1

if you got it wrong then you must mean
f = F/(d-F)

in which case you should multiply both sides by (d-F)
\[ f(d-F)= F \]
distribute the f
\[ fd - Ff = F\]
add Fd to both sides
\[ fd = F + Fd \\ d = \frac{F+Ff}{f}\\
d= F \frac{(1+f)}{f}
\]

Answer 2

okay, see i multipledbutdid know what to do after cause i'm new to this
