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 WebIn mathematics and particularly in algebra, a system of equations (either linear or nonlinear) is called consistent if there is at least one set of values for the unknowns that satisfies each equation in the system—that is, when substituted into each of the equations, they make each equation hold true as an identity. rawlplug brown 67-231

WebSep 17, 2024 · If the matrix vector equation A x → = b → is consistent, then the steps involved in putting [ A b →] into reduced row echelon form depend only on A; it does not matter what b → is. So when we put the two matrices [ 1 2 3 3 4 7] and [ 1 2 1 3 4 1] from above into reduced row echelon form, we performed exactly the same steps! WebGauss-Jordan is augmented by an n x n identity matrix, which will yield the inverse of the original matrix as the original matrix is manipulated into the identity matrix. In the case that Sal is discussing above, we are augmenting with the linear "answers", and solving for the variables (in this case, x_1, x_2, x_3, x_4) when we get to row ...
