OK, ready to go!  Let's start by doing some that are already in the nice forms:

We can't solve anything with this
obnoxious Log in here -- he's blocking
the x!  So...  We need to get rid
 of him.  And who can do that?
His inverse!

So...  Zap both sides with

!

With that inverse trick, these are really pretty simple.

Let's do some more:

Remember that this is really

Hit it with the inverse:
