Solve the system. If the system has one unique solution, write the solution set
whether the system is inconsistent, or the equations are dependent.
-4x - 5y - 3z = -21
-4x +y - 12z = -51
3x +6y +3z = 21

Which one of the following is correct?
The system has one solution.
The solution set is {…}

The system has no solution.
The system is inconsistent.
The equations are dependent.


The system has infinitely many solutions.
The system is inconsistent.
The equations are dependent.
