Webfor any m n matrix A: (a) For every b, the equation Ax = b has a solution. (b) Every column vector b (with m entries) is a linear combination of the columns of A. (c) The columns of A span Rm (this is just a restatement of (b), once you know what the word \span" means). (d) A has a pivot in every row. WebHere the number of unknowns is 3. So, if the system is consistent and has a non-trivial solution, then the rank of the coefficient matrix is equal to the rank of the augmented matrix and is less than 3. So the determinant of the coefficient matrix should be 0. Hence we get
