If at all, you'd have to find an approximate solution by iterative processes. Actually that means a trial and error process where you try a number. Then if it fails to satisfy the equation, you try another number. Each time you observe how close you came to 0, and then you judge from that whether you should try something larger or something smaller. Each time you get closed and closer to 0. The equation is too complicated for a TI calculator, or even Wolframalpha. So you would have to calculate it each time in parts. Edwin
