    Please confirm that what you meant is this:



    Is this exactly how the problem was presented to you? Because this is an unusual problem, and in fact I don't believe it has a unique solution, so before going too far down the wrong path I just want to make sure we are on the same page.

    Just as a guess - I wonder if the original problem was actually this:



    Is my guess correct?

    Unfortunately the correct answer is "none of the above." Of course x cannot = 1, because then the log(x) = 0 and the first term would have a zero in the denominator. Other than that - it can be shown that the value for 'x' is not defined unless the values for y, z, and t are set. So there is not a unique answer to the problem as written.
