This is really helpful to my study. I am grateful for your explanation!
much thanks to you teacher
Isnt the first row supposed to start with a 1?
If it stated to write the augmented matrix in REF or RREF form, then yes. I just stopped as soon as I saw that x2=0.
This is really helpful. Thanks a bunch !!!😊
Thanks
Thank you
But we can make that coefficient matrix in to an identity matrix, then it will be more easy.
He used the Gauss method to obtain an REF. What you are suggesting is the Gauss Jordan method which will give an RREF, which is correct. A couple steps are the REF can obtain the RREF. Both the REF and RREF can solve the system for us.
