Unterbestimmtes Gleichungssystem lösen | Verständlich erklärt

It explains clearly how to solve an underdetermined system of equations. A system of linear equations is underdetermined whenever there are more variables than equations within the system of equations. To solve an underdetermined system of linear equations, you can first specify any variable. This yields a definite system of equations with as many equations as variables. This can then be solved using familiar methods (e.g., the addition method). The solutions obtained in this way, together with the solution for the one variable specified at the beginning, form the solution set of the system of equations. I will explain the procedure in detail using an example problem.
