Abstract
We describe experiments for learning how to solve linear equations equations by means of the numeric method of table refinement, the graphical method of intersection point deter-mination, and the algebraic method of equivalence transformations. In addition our approach follows the educational concepts of visualization and the scaffolding method. Instructions are given for solving linear equations with integral, fractional, and algebraic coefficients. Degenerate equations are also discussed.
