| Abstract: | Instead of the classical method to solve linear equations. we give a simple method in this paper. If the coefficient matrix A of linear equations Ax=0 is reduced to then the basic solution matrix of Ax=0 is or its row-exchanged form. The basic solution matrix of Ax=b can be constructed in a similar way, i. e. if (A. b) is reduced to , then linear equations Ax=b has a basic solution main, row-exchanged form. |
