Any idea how would I solve such a problem?
Substitute a semi-random range of numerical values for each variable into both equations and evaluate them. If the both result in the same answer, for a well-chosen set of inputs, they're probably the same equation.
Of course, that kind of just moves the goal posts a little to one of coming up with a good set of values; but given the performance of modern processors, unless these are quite complicated formulae, you can probably afford to throw a little (or even quite a lot) of everything at them and still get a statistically, highly probable answer in a few seconds.
