Determine whether the following system has a unique solution, no solution, or infinitely many solutions. If a solution exists, write it down.

No for its augmented matrix 



in row reduced echelon form becomes:



and the bottom row translates as 



and there is no possible value for  such
that when it is multiplied by 0 you will get 1.
So there is no solution.
