Ok how would you find out what X is if you know Y and Z

I'm curious.... Is this a question based somewhat more on number theory? Or is it more literal. You haven't given any context for the question so it's hard to decide in which direction to approach the answer. Your user name suggests you know how to do basic algebra and the relation between the variables is of paramount importance. So since you left it out it leads me to believe either you're being rhetorical in a sense (maybe even mocking) or that you're trying to see if any one knows the general method of finding the answer to arbitrary numbers given the parameters that y and z are known with no further context or relation to x. I'm sure I can come up with a methodology for finding x (or likelihoods of x) given two known paramaters where x is not known, however my initial work up is designed around the idea that through manipulating y and z the "calculator" will be able to determine if x has been found. In other words the methods are based on the fact that the context is not known to begin with but WHEN known the answer will be apparent. This methodolgy even goes beyond numbers saying strictly that if events x, y and z are measurable (in some quantitative or qualitative way) and they are relatable (quantiatively or qualitatively) then x can be found as long as y and z are known. That being said, I say "initial work up" because just beginning to define the possible relationships of x to y and z (and y to z for that matter) is becoming very complex after a few initial steps. With all the known operands of how to compare three numbers with each other (especially considering the multitude of ways in which the operands can be compounded), the more complex the value of the variables means the more complex the solution will be. With no context, essentially I see an infinite set of possibilities. (or near infinite). If you already have the solution and are proposing the question not as a solicitation for assistance in finding the solution but as a method of testing the knowledge of this demographic than I'd be delighted to hear the solution. If you are seeking a generalized way to approach the problem from an arbitrary set of context than please say so. Otherwise could you please provide as much context as you can (or are willing) to eliminate unnecessary diversions. :)

Fazendo o isolamento de F:

F = ( A - B + F ) / 3

F / 3 = A - B + F

B - A = F - ( F / 3 )

B - A = 2F / 3

F = ( 3 * ( B - A)) / 2

It looks like your calculations are incorrect. If you are trying to isolate the F, then the calculations should run like this:

F = (A - B + F) / 3

F*3 = A - B + F

3F - F = A - B

2F = A - B

F = (A - B) / 2

Of course if you incorrectly typed the first line of the equation and it was supposed to read : F = (A - B + F) * 3

Then it would follow:

F/3 = A - B + F

F/3 - F = A - B

2/3(F) = A - B

F = (A - B) * (3/2)

OR: F = ((A - B) * 3) / 2

The last line can be either expression because the order of operations outside of (A - B) is irrelevant because of the commutative law of multiplication and division. The first way is easier for me to read and conceptualize though so I personally prefer it.

You mentioned something about excel. I don't use excel on a regular basis. I use programming for all my math using Visual Basic or Java. Also, I don't understand what your equation means or does. Does F = Frequency? What is A and what is B? And where does the 3 come from? How did you come up with the original equation or where did you find it? And what data set would you use this equation on?
