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).
Linear algebra is the study of linear sets of equations and their transformation properties. Linear algebra, sometimes disguised as matrix theory, considers sets and functions, which preserve linear structure.

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.
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 ...
A system of linear equations (or linear system) is a flnite collection of linear equations in same variables. For instance, a linear system of m equations in n variables x 1 ;x 2 ;:::;x n can be written as
1.1 Introduction to Systems of Linear Equations a linear equation in n variables: a 1,a 2,a 3,…,a n, b: real number a 1: leading coefficient x 1: leading variable Notes: (1) Linear equations have no products or roots of variables and no variables involved in trigonometric, exponential, or logarithmic functions.
