Find all solutions of the system (E) of linear equations 109z + 30y + 25z 6. -25z 7y + 6z ly + 12 Answer, step 1: The RREF of the augmented coefficient matrix of (E) is. Answer, step 1: (enter 1' for a true answer, and enter '0' for a false answer). The system (E) has infinitely many solutions The system (E) has exactly one solution The system (E) has no solutions Moreover, these solutions are: t + span{a, b} for nonparallel vectors a and b. For a vector that's not applicable. enter -99' in each of its positions: if you mark a inapplicable, then b must be inapplicable also. b = Check
