Expert Solution
Step 1: Definition

Let Ax=b be a system of linear equations,  then 

(*) If rank(A|b)=rank(A) , then system is consistent and 

  •  If  If rank(A|b)=rank(A) = number of unknowns,  Then system has unique solution. 
  • If If rank(A|b)=rank(A) < number of unknowns,  Then the system has infinitely many solutions. 

(**) If If rank(A|b)≠rank(A) , then system is inconsistent and has no solution.
