    I wonder if that was the first take 🙂

    What about if you had a 4×4 system? or nxn system? how do you solve it?

    Use the Jordan-Gauss elimination, the easy way to solve the system 4×4, or even 10×10.
    Form the augmented matrix , enter the matrix in MATLAB. and then use this simple code(rref(A)), where A is the augmented matrix….

    Gaussian elimination is much easier

    for the minor matrix at min 4:00 you would better write the minor matrices themselves then calculate'em later

    Old video, but… THANK YOU! When I was learning vector/matrix algebra by hand in the 1980's, I always knew how to solve the problems but invariable made minor arithmetic errors. It's great to see a Maths instructor acknowledge this. Computers are SO much more reliable for simple repetitive tasks than humans.
