Solve the following problems, showing any necessary work. This includes row operations. 1. [1 point] How many solutions does each of the following systems of linear equations have? • If there are no solutions, circle the row that indicates that there are no solutions. . If there is exactly one solution, circle the pivots. • If there is more than one solution, circle the columns which do not have pivots in them. 1-3-2-1 121 0 1 0-3 0 0 1-2 0 0 0 a. b.
