**Lecture 3 Linear Equations and Matrices**

• Use matrices and Gaussian elimination to solve systems of linear equations. • Use matrices and Gauss-Jordan elimination to solve systems of linear equations. What You Should Learn . 3 Matrices . 4 Matrices A matrix having m rows and n columns is said to be of order m n. If m = n, the matrix is square of order m m (or n n). For a square matrix, the entries a 11, a 22, a 33, . . . are the... Solving Systems Using Augmented Matrices USING ELEMENTARY ROW OPERATIONS A matrix containing the coefficient matrix and the matrix of constants for a system of linear equations is called the of the system. LINEAR SYSTEM AUGMENTED MATRIX Recall from Chapter 3 that equations in a system can be multiplied by a constant, or a multiple of one equation can be added to another equation…
