The reduced row echelon form of a system of linear equations in x and in x, y and z is given. For each system, determine whether it has a unique solution, infinitely many solutions, or no solutions. (a) A. Infinitely many solutions B. No solutions C. Unique solution: x = 0, y = 0, z = 0 D. Unique solution: x = -2, y = -4 E. Unique solution: x = -4, y = -2 F. None of the above
