Finding a parametric description of the solution set of a linear system is the same as solving the system. Is this statement true or​ false? - Answer The statement is false. The solution set of a linear system can only be expressed using a parametric description if the system has at least one solution. If one row in an echelon form of an augmented matrix is [ 0 0 0 5 0 ] then the associated linear system is inconsistent. Is this statement true or​ false? - Answer The statement is fals...
