1 Unit - 8 video lessons
What is a Linear Equation?
In this video, you will learn about linear equations in two variables, three variables, and four variables with examples. Sometimes, we use the word ‘unknowns’ instead of the word ‘variable’. I will also give you examples of nonlinear equations, and you will learn about a solution to linear equations with examples.
06:01
Linear Systems
A linear system is a collection of one or more linear equations involving the same variables. A solution to the linear system is a sequence that satisfies each equation in the system. In this video, you will learn about the linear systems with examples, solutions to the linear system with examples, and the solution set of a linear system.
08:39
The Elimination Method
The elimination method is useful for solving small linear systems. In particular, the elimination method works really well for solving systems of two equations with two variables. In this video, you will learn how to solve linear equations using elimination methods with examples.
09:17
Echelon Form
A matrix is in row echelon form if it satisfies three conditions. In this video, you will learn about the three conditions satisfied for a matrix to be in row echelon form with examples.
11:46
Row Reduction
Row reduction is a 4-step algorithm used to produce a matrix in row echelon form. This algorithm is also known as Gaussian elimination. A 5th step can be added to produce a matrix in reduced row echelon form. In this case, the algorithm is called Gauss-Jordan Reduction. In this video, I will use an example to walk you through the algorithm of row reduction. I will show you how to do both Gaussian elimination and Gauss-Jordan reduction.
12:04
More Examples of Row Reduction
In this video, I am going to go through 2 more examples of the row reduction algorithm by following the rules step-by-step.
