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.
Chapter 3: 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.

Linear Equation and Solutions. A linear equation in unknowns x1; x2; xn is an equation that . . can be put in the standard form ; a1x1 þ a2x2 þþ. anxn 1⁄4 b. ð31Þ : where a1; a2; . . . ; an, and b are constants. The constant ak is called the coefficient of xk, and b is called the constant term of the equation.
equation is a system consisting of one linear equation in four variables. In this class we will be more interested in the nature of the solutions rather than the exact solutions themselves.
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.
