Explaining Newton's method would take too long.
Try a numerical analysis textbook (or get a copy of my book Excel for Sci &
Engineers)
You might be able to solve your problem with Solver but you need to do some
work first.
best wishes

I have an equation in which i want to solve for a variable that is
contained
in both a linear function and a natural log function. I have been told I
need to use Newtons method but dont know how to do this. Can anybody help?
