The Keys Method: An Innovative Approach to Solving Equations with Multiple Unknowns

This research presents the Keys Method, a scientific and logical approach for solving mathematical equations from two unknowns up to several unknowns. The method relies on two main divisions: the numerical set (natural, integer, rational, radical) and the flexible numerical system, applying the fourth key to extract balanced and consistent solutions within the bounds of the numerical set. The study includes: Practical examples for all types of numbers (natural, integer, rational, radical) Explanation of balanced and unbalanced cases for unknowns Guidelines for choosing lower or higher numerical systems depending on the operation type (addition or subtraction) Notes on the appearance of zeros, repeated numbers, or constants when numbers are unbalanced The method is applicable in educational and scientific contexts, simplifying equation solving in an organized manner without the need for additional equations or methods.
