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? - 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 inconsi...
