The reduced row echelon form of a system of linear equations in x and y or in x, y and z is given. For each system, determine whether it has a unique solution (in this case, find the solution), infinitely many solutions, or no solutions. [1 0 0 0 1 0 0 0 0 | -1 2 0] A. Infinitely many solutions B. Unique solution: x = 2, y = -1 C. No solutions D. Unique solution: x = -1, y = 2 E. Unique solution: x = 0, y = 0, z = 0 F. None of the above [1 0 0 0 1 0 | 0 0 0] A. Unique solution: x = 0, y = 0 B. No solutions C. Unique solution: x = 1, y = 1, z = 0 D. Unique solution: x = 0, y = 0, z = 0 E. Infinitely many solutions F. None of the above [1 0 0 0 1 0 0 0 0 | -2 -2 3] A. Unique solution: x = -2, y = -2 B. Unique solution: x = -2, y = -2, z = 0 C. Infinitely many solutions D. No solutions E. Unique solution: x = -2, y = -2, z = 3 F. None of the above
