Sir your what's app number please

ty so muchπ€π€π€ sir

your a great teacher

You can do this with any 3 equations right?

No one here has to be sooo happy , he has done a mistake . x=-1 not 1

I was struck at this for hours now, this got cleared in a few minutes, thanks a lot sir !

You, my good sir, are THE GOAT

Thank you professor, touchdown

I have a test on this next week! thx dude

I still dont get it wwhyyyyyy

Love ur lectures!!! Thannnkss!!!

I'm ur student, from India , respect u sir, thank you for the video,

Thanks for this perfect video

Thank you so much for teaching this ! Before I found this video I was struggling doing ero . But now I can do it smoothly . π

Why couldn't you just do R1-R3, instead of R1 + -R3

You could teach differential equations to a 5 year old. Awesome video sir. Thanks!

Excellent Explanation , just wanted to know that if i'm getting 1's diagonally but my values are different of x , y and z , will it still be correct

Tq, it's so easy to understand π

Thank you so much!! I was so confused for days but now I finally figured out how to solve it π

THANK YOU SO MUCH

in the first step, why did you call the 6 a negative 6?

whowwww coooooooooool!!!! when I was introduced to this topic and hour ago, I was confused, but thanks for making it clear now

Bless your soul you're a hero

THIS IS THE BEST EXAMPLE SO FAR I GOT FROM YOUTUBE! THANKYOU SIR.

ππππππyou made this so easy to understand thank you

nice

Thank you so much

Thank you!!

He is showing you that he understands it .He is not teaching you.

There is a difference.

Why are math people so bad at teaching ?

Way too fast!!!

Thank you Sir. May Allah reward you.

nice

Thank you so much for this video, it really helped me understand the concept for tomorrow's test! My teacher made it really confusing, and you cleared it up really well!!!

Sir y u start on last ro ?

And

Y u not star on any row ?

Thank you!

Just a quick question: If you were to perform row operations on Row 1 and Row 2, could you choose whether to put the answer in row 1 or row 2 or is there a specified row the answer should go on?

watched so many vids on this type of question, including khan academy. THIS IS THE BEST ONE. THANK YOU SOOOOOOO MUCH

Quick questn: is the order of the first augmented matrix a 3×3? Or 3×4?

Does this work for things like a 2×3?

Thank you Mario

Thankyou so much

Thank you β€οΈ

Thank you!

Instead of doing 3R1+R2=R1, couldnt you have just multiplied R1 by -1/2, R2 by 1/6, and R3 by 1/2?
