Answer by nerdybill(7384) (Show Source): You can put this solution on YOUR website!
Ln x-Ln(x+1)=2
Ln x/(x+1)=2
x/(x+1)=e^2
x=e^2(x+1)
x=xe^2+e^2
x-xe^2=e^2
x(1-e^2)=e^2
x = e^2/(1-e^2)
x = -1.157
Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!
Ln x-Ln(x+1)=2
ln[x/(x+1)] = 2
x/(x+1) = e^2
x = (e^2)x + e^2
(1-e^2)x = e^2
x = -1.1565176
------------------
But ln of a negative does not exist.
So, there are no solutions.
