How do you solve log4 3-x -log2 x-1 0?

Unfortunately, the browser used by Answers.com for posting questions is incapable of accepting mathematical symbols. This means that we cannot see the mathematically critical parts of the question. We are, therefore unable to determine what exactly the question is about and so cannot give a proper answer to your question.

In this question, for example, it is not clear whether the characters immediately after "log" are the bases. Also, it is unclear whether the first "term" is log(3-x) or log(3)-x: both logs to base 4.
