Unformatted text preview: rows. 5. Start with the rightmost pivot, work upward and to the left, and make zeros above each pivot. Make each pivot a 1 by dividing its row by its value when necessary. Find the general solutions of the systems whose augmented matrices are given. Indicate the pivot positions and the pivot columns. 1 0 3 2 08 0 0 1 0 2 3 0 0 0 0 1 1 0 0 0 0 0 1 3 5 2 2 8 18 10 3 13 31 18 Suppose a 3 5 coecient matrix for a system has three pivot columns.
