log(x+5)-log(x-3)=log5
want to get checked!
logx-3/x+5=log5
drop the log .
x-3/x+5=5
(x+5)*(x-3/x+5)=5(x+5)
x-3=5x+25
-28=4x
x=-7

logx-3/x+5=log5
Is this step correct?

parthkohli · Answer

Just check it by inputting the following into the calculator.

$ \color{Black}{\Rightarrow (\log (-7) + 5) - (\log(-7) - 3)}$ and $\log5$

Check if they give the same result.

I think it should have been logx+5/x-3=log5

anonymous · Answer

make sure it's non negative too.
