WebA system of linear equations with coe cient matrix A will be inconsistent for certain values on the right hand side if the row echelon form of A contains a row of zeros. If the row echelon form of the coe cient matrix A does not contain a row of zeros, then the system is always consistent, regardless of what the right hand side is. WebIf a system has at least one solution, then it is said to be consistent. If a system has no solutions, then it is inconsistent. A consistent system has either 1. exactly one solution (no free variables), 2. in nitely many solutions (because there is at least one free variable). A matrix is in reduced row echelon form if all of the
