Solving a system of 3 equations and 4 variables using matrix row-echelon form

SOLVED: 2. The augmented matrix of a linear system has been transformed by row operations into the form below. Determine if the system is consistent. [ 1 5 2 -6 0 4 -7 2 0 0 5 0 ]

The augmented matrix for a linear 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. (a) [ 1 * * * 0 1 * * 0 0 1 1] (b) [ 1 0 0 * 1 0 * * 1 *] (c) [ 1 0 0 0 1 0 0 1 1 * *
