The equation solver can solve **linear equation systems**. The coefficients of the equations
are specified within a data grid. The number of equations is selectable and corresponds to the number of
solution variables x_{1} to x_{n}.

Features:

- Systems of linear equations with up to 25 equations and variables can be solved.
- Using rational numbers a linear equation system can be solved exactly and without rounding errors.
- For linear equation systems which don't have a unique solution a parameter solution is calculated.
- Systems of linear equations can be loaded from CSV files and stored to CSV files. CSV files can also be processed with Microsoft Excel.
