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.

In mathematics, a system of linear equations (or linear system) is a collection of two or more linear equations involving the same variables. [1][2] For example, is a system of three equations in the three variables x, y, z.
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.
