Hi, I just don't get this sort of Logarithm problems that have same two variable in the equation. The problem is: Solve for x log x + log(x+3)=1 thanks for the help =]

The problem is: Solve for x log x + log(x+3)=1 thanks for the help =] Rewrite using log properties rewrite in expo form. So x=2 or x=-5 But if you plug x=-5 into the original equation you end up with the log(-5) which is undefined. So the only solution is x=2.
