What equation are you talking about? I don't see one.

the equation is secret/hidden.

one can only use the variables to work out the actual equation.
it's not very easy.

I solved one before which the function was a very simple straight line (linear equation), but this one is more complicated.

i have a feeling it's a quadratic or cubic equation.

Can you label your columns on your table then? I'm not sure what to make of what you've posted so far.

There seems to be some sort of random process going on. Otherwise how do you get different answers from identical input?

Based on the information you gave, I would have to say you have an inconsistent system so no solution. Perhaps you misunderstood the problem. Perhaps it is something on the lines that you are given various data from a sample population and are asked to create a mathematical model approximating the information. That would make more sense. At any rate, I do not foresee the variable with a 0 value affecting the system at all so that leaves us with 2 variables to worry about. Now considering the other two variables, the "mystery" operation results in a given output that ranges from 0.74 to 0.88. Now those values have a strong resemblance to percentages, perhaps test scores. Another possibility is that we are looking at some kind of "game" in which one of the 2 values are picked "randomly" and the right column shows the winning percentage - i.e. this could well be a gambling game of some kind. However, without further information it is impossible to give an absolute answer besides that I am nearly certain that you are not going to find any normal algebraic expression that fits your given criteria.
