In this lecture we will discuss some ways in which systems of linear equations arise, how to solve them, and how their solutions can be interpreted geometrically. Linear equations: line in R2 (2-dimensions) can be represented by an equation of the form a x + a y = b. 2. (where a 1, a2 not both zero).
A comprehensive study of linear systems leads to a rich, formal structure to analytic geometry and solutions to 2x2 and 3x3 systems of linear equations learned in previous classes.
Solving System of Linear Equations S1: Definition of a Matrix, and Types of Matrices Definitions 3.1.1: A matrix is a rectangular array of numbers enclosed in parentheses. The numbers occurring in a matrix are called the entries. Each matrix has a certain number of rows and a certain number of columns.

Systems of linear equations play an important and motivating role in the subject of linear algebra. In fact, many problems in linear algebra reduce to finding the solution of a system of linear equations.
1. Systems of linear equations We are interested in the solutions to systems of linear equations. A linear equation is of the form 3x 5y + 2z + w = 3: The key thing is that we don’t multiply the variables together nor do we raise powers, nor takes logs or introduce sine and cosines. A system of linear equations is of the form 3x 5y + 2z = 3 ...
