In each part of Exercises 23-24, the augmented matrix for a lin-
ear system is given in which the asterisk represents an unspecified
real number. Determine whether the system is consistent, and if so
whether the solution is unique. Answer "inconclusive" if there is not
enough information to make a decision.
