can R solve these paired equations
Hello [An answer was posted just now using numerical ideas; here is an answer from a symbolic perspective] These equations involve x^y in more than one unknown, so inverse functions cannot be used. I do not think you will be able to characterize even the number of solutions, let alone their nature. To see the difficulty, look at the Lambert W function. My advice would be to simplify, simplify, simplify your problem as far as possible; remove terms successively until you are left with a trivial system, then add *one* term and see if this produces any insights.
