Suppose that the reduced row echelon form of the augmented matrix associated 101 0 with the system of linear equations is 01 -1 0 . Using the variables , 0 0 1 y, and 2 what is the solution to the system of equations? Ox = 0, y = 0, z=0 Ox = -z, y = z where Z is arbitrary Ox = z, y = - Z where Z is arbitrary the system is inconsistent none of the above
