Hi there, 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? ** It is my first post in this forum, and I saw some other similar threads in this part of forum. However, I am not sure if I did post it in the right place, hope I did not violate any rules.
