$\displaystyle y= \frac{r+x}{1-rx}$

$\displaystyle y(1-rx)=(r+x)$

$\displaystyle y-yrx = r+ x$

$\displaystyle y-r = x+ yrx$

$\displaystyle y-r = x(1+ yr)$

$\displaystyle x= \frac{y-r}{1+yr}$ - Mar 16th 2010, 07:22 PMfletch
thanks anon.1 getting back into maths after 10 years and some things appear harder than they actually are.
