Abstract
Cramer's Rule is a fundamental rule for solving linear equations. No matter what tools are used, such as matr, the final solution to the problem is still by Cramer's Rule.《The Linear Algebra》,which published by Tongji University, gives a necessary condition about deduction of the Rule. Due to the arrangement of the chapters, it is just pointed out that the sufficient conditions which hasn't been proved are established. Because the theory of linear e-quations haven't been provided. In this paper, Two kinds of methods are given.关键词
