摘要
关于ｎ个未知量ｍ个方程的非齐次线性方程组有解的充分必要条件，我们已有几个定理。在本文中，我们介绍二个新的定理和一种通过解齐次线性方程组而得到的新解法。
Some theorems on the necessary and sufficient sondition which aninhomogeneous linear system of m equations of n unicnowns has a solution have been ob-tained,Two new theorems and one new solution method by soluting a homogeneous linearsystem were introduced.
