115 C H A P T E R 3 Linear Equations and Matrices In this chapter we introduce matrices via the theory of simultaneous linear equations. This method has the advantage of leading in a natural way to the concept of the reduced row-echelon form of a matrix. In addition, we will for-mulate some of the basic results dealing with the existence and uniqueness of systems of linear equations.
