The Solving of an Equation with a Three Unknown in Set of Natural Numbers

The solving equations of the type (*) we do not find everywhere. In a recent paper, in 2015, we have presented an inductive solving using “the method of divisors” and “the method of inequalities between unknown” in the set of natural numbers of this class of equations in two variables. In this paper, using the same methods, we tackle in a deductive way the problem of solving equations of type (*), in three variables, that is we propose the solving of the general equation (**) after which we can deduce easily, way of solving the all these types of equations.
