solveLinEqs calculates a solution to a set linear equations that belong to the Rationals, if one exists. It does this by using the type num/den to calculate the solution, where num is an unlimited number of integers. There are no limits to the number linear equations that can be solved. If the coefficient matrix contains zero determinant, the matrix is augmented by the right-hand side vector or matrix and its reduced row count form is output. This can be used for determining if the equations have self-consistent. The output is displayed in floating point at any precision. A second window displays the output. A third window allows you to do arithmetic using fractions of unlimited length numerators or denominators. The Help menu explains how to use solveLinEqs.
