(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Solve 3 equations in three unknowns I, W, and L to find the critical value of L.

***Please See attachment 'differential.gif'****

also note, that I wrote all this using 'mathtype', if its of importance for any to know.

2. Relevant equations

Please see attachment 'differential.gif'

3. The attempt at a solution

****Please see attachment 'Differential tryout.gif' and 'Differential Tryout2.gif'***

I squeezed my brain to what it can handle, but I can not understand how the textbook has got such a solution by its process which I do not understand------Please see attachment 'Differential textSolution.gif' ( since their is a max of three attachments, I am gona make a new thread named 'Differential Text sol' with the attachment.
