I've tried this problem at least 5 times and I still can't get to the right answer ln(x+1)-1=ln(x-1) I know the correct answer is x=(e+1)/(e-1), I just can't get it. Thanks

$\displaystyle ln(x+1) -1 = ln(x -1) $ Combine like terms $\displaystyle ln(x+1) - ln(x-1) = 1 $ Now use the identity that $\displaystyle ln(a) - ln(b) = ln(\frac{a}{b}) $.
Oh yes, thank you! I had my properties backwards.
