I have a problem solving equations involving for example: ln((e^x)+1) = ln(e^x) + 1

How do I simplify this expression, or any expression involving ln(x + a)

If you rewrite the first equation as

[tex]

\ln{(e^x+1)} - \ln{e^x} = 1

[/tex]

you can use properties of logarithms to simplify the left side. Once that's done you should be able to proceed.
