Using Gauss Jordan Elimination to Solve a System of Linear Equations | mathwithjanine

Показать описание
In this video tutorial, I demonstrate how to solve a system of linear equations with 3 equations and 3 unknowns. To solve a system of 3 equations and 3 unknowns we need to write the coefficients of our equations in the form of an augmented matrix. Next, we will use row operations to get our augmented matrix into row echelon form. Once our matrix is in row echelon form, we can solve for our 3 unknowns.

Excellent! I like the fact that you did every operation. Your layout of information on the board was perfect I thought. I hope you keep making videos :-). By the way, I found you through your comment on Peyam’s video on dominated convergence.

LOLLLL. I found the channel through a comment on Peyam's channel too!!! Hehehehe :3
I hope you make more videos too. Youtube needs more math channels - silly youtube algorithm. Subscribed :)
