Rearranging an equation

Would anybody be able to rearrange this equation for me, to make r=.

P= (c/m)* (1/(1-(r/m)^n)) +(F/(1+r/m)^n)

All help would be fantastic, ive attempted this so many times, but just cannot do it :frown:

Noble.

Please post this in the academic subsection of the Maths forum, specifically here:

Unparseable latex formula:

P=\dfrac{c}{m} \left( \dfrac{1} {1- \left( \dfrac{r}{m} \right) ^n \right) } + \dfrac{F} {\left( 1+ \dfrac{r}{m} \right) ^n }

Does that look right?
Are you sure you haven't posted one of the denominators wrong?

I believe it should be

Unparseable latex formula:

P=\dfrac{c}{m} \left( \dfrac{1} {1- \left( \dfrac{r}{m} \right) ^n \right) } + \dfrac{F} {\left 1+ (\dfrac{r}{m} \right) ^n }

If I am correct, what if you multiply and divide

Unparseable latex formula:

\dfrac{c}{m} \left( \dfrac{1} {1- \left( \dfrac{r}{m} \right) ^n \right) }

for

1+ \left( \dfrac{r}{m} \right) ^n

and

\dfrac{F} {\left( 1+ \dfrac{r}{m} \right) ^n }

for

1- \left( \dfrac{r}{m} \right) ^n

?

Hope that helps.
