Use row operations to solve the system.
x + y – z = 5
2x – y + z = -11
x – 4 + 3z = -41
A. The system has exactly one solution. The solution is : (____, _____, _____) (write an exact answer in a simplified form).
B. This system has infinitely many solutions of the form (__, ___, z), where z is any real number. (type expressions using z as the variable)
C. This system has no solution.
