Abstract

The paper presents the solving of linear three variables system using two methods: analytic and graphic methods. The solving of a such system implies four cases: compatible system with unique solution, simple-indeterminate compatible system, double-indeterminate compatible system and incompatible (impossible) system. The correspondence between the analytic (synthetic) method and the graphic (visual) method is evident for the three space fundamental elements: point, line and plane.
