Initial Approaches to Solve Problems of Three Linear Equations Systems Using a Linear Programing Graphical Method

The following work shows one of the rst successful attempts to solve problems in applied linear programming which use equation systems with three variables using a graphic method. In order to have a successful application of that sort of method, the use of descriptive geometry and perspective methods to add and substract volume was used. The applications of the proposed method can be extended to any rst degree, three variables equations system, yet the application of this method has an immediate impact in linear programming especially for academic purposes
