Linear equations form the basis of linear programming. If you have a good understanding of the Gauss-Jordan method for solving linear equations, then you can also understand the solution of linear programs. In addition, this chapter introduces matrix notation and concepts that will be used in Chapters 3 and 4 (optimizing functions of several variables).
