The best thing about the entire matrix series is, that now I can see the whole picture of it's relation with the system of linear equation and why we do what we do. Thank you Ciaran. I truly want more videos on many other topics of mathematics too. You are doing great work. I don't know why we still have less views this series. I am excited to learn more from you!
That's a very kind comment pal, thank you. I'm pleased to hear you're learning from and enjoying my videos. And yes I will gradually add to the series, covering other topics typically found in engineering maths, so stay tuned.
I'm getting ok at this and I'm dying to use it in real life. But in the text books all the questions are in row vector form eg: -2x +3y = 7 and 3x -7y = -8 where putting it in a matrix is easy. And so, we can find the rref or just take the reciprocal of the determinant with an flipped matrix to find the inv matrix and get where the lines cross. Which is all fab. Then my son has a gcse question which is y = 2x + 3 and y = -0.5x -1. Let's say these lines intercept. How can I express this as a [augmented] matrix and find where the lines cross?? So frustrating that I can't figure this out...

Superb tutorial though! I must go through your videos.
