SOLVED:The augmented matrices that follow are in row echelon form. For each case, indicate whether the corresponding linear system is consistent. If the system has a unique solution, find it. (a) ( 1 2 4 0 1 3 0 0 1) (b) ( 1 3 1 0 1 -1 0 0 0) (c) ( 1 -2 4 1 0 0 1 3 0 0 0 0) (d) ( 1 -2 2 -2 0 1 -1 3 0 0 1 2) (e) ( 1 3

SOLVED:Can any system of linear equations be written as an augmented matrix? Explain why or why not. Explain how to write that augmented matrix.
