10 years later and now I need it, thanks a lot

[plzr]

wow. i literally signed into this account i made years ago just to thank you. first ever comment on you tube but mate you deserve it. great video taught me all i need to know that my lecturer couldn't in weeks. A++

You make it seem so easy, I don't know why but I can't do any problem that involves 3 equations no matter what method I try to use

thanks, helped me a lot with inverse matrices

[MrStanislow]

Correct. Typically, getting a matrix into row echelon is much easier than getting it into reduced row echelon.

[liammcdonough]

what do you do when one of the rows is all zero

[adriandelpino]

thank you but i haven't learnt anything from this video

D wasnt rref because row 1 was 1 3 0 * not 1 0 0 *
