Hi there,(adsbygoogle = window.adsbygoogle || []).push({});

I do not know why, but I cannot get to the solution of the following equation.

The equation is :

(m*x+m[p]*x[p])/(m+m[p]) = 0

And, I know that if this is solved for x[p], it will get to : x[p] = -x m/m[p] (Written in Textbook, and I checked it using Maple)

However, I tried times and times, but I could not get to the correct answer through the steps. Each time I tried I got to : x[p] = 1 + ( 1 - x)m/m[p]

Can someone show me the steps here please?
