I am a bit ashamed for asking such a simple question, but we really need the answer.
We develop a program to calculate... something for our clients (I would be hard pressed to explain it in english, but in french : calculer les cotisations des adhérents pour des associations professionnelles).
The equation given by our client is simple :
$\mbox{cotisation}= \frac{x}{1.5 + 0.02 x} \times 1000$
But in order for it to fit in our program, we need it in this form :
$\mbox{cotisation} = (x - p - m) \times c + d + f$
The x's are the same variable in the two equations.
In the second equation, the other variables are replaced by fixed numbers when the program is launched.
So, in other words, we only need to get x outside the fraction in the first equation.
Apparently none of us around here remembers enough math to be able to do it... :(
Yes, we will buy ourselves a "math for dummies" book. But in the meantime, could you help us ?
Thanks
