Textbook Question

Chapter 3.2, Problem 13P

For each of the following problems write and row reduce the augmented matrix to find out whether the given set of equations exactly one solution, no solutions, or an infinite set of solutions. Check your results by computer. Warning hint: Be sure your equations are written in standard form. Comment: Remember that the point of doing these problems is not just to get an answer (which your computer will give you), but to become familiar with the ideas, and notation we are using.
