Solving Systems of Equations Using Augmented Matrices

Shows how to solve a system of equations in two variables using augmented matrices. Also reviews matrix row operations and row echelon form for a 2 by 3 matrix.

I've been trying to understand this for a while and I have to give up credit for having the clearest explanation of this process. The most helpful is when you wrote the steps in blue to show the work. As another person said, the volume was low.

Thank you very much for your great explanation!

You are like the only teacher who explains it

I made a code in Javascript using this explanation thanks <3.

Dude that was awesome. Almost got lost when you were using the fractions, but I was alright. Trying to study for the 基本情報技術者試験, and this kind of math is in it. I like how you dress up like an OG teacher too. Anyway, thank you! Gonna make some practice problems for myself now...

I appreciate you making this video my friend

Awesome vid! You saved my cousin from imminent doom for his MAP

Thanks you're a better teacher than my math teacher

[MrJediBlake]

Helped me understand this allot better and I can now complete matrices, thanks!

[AP-qnmf]

this was very helpful, it made me realise where i made a dumb math typo :)

[hibahx]

Thank you! This helped so much. I was so confused about row echelon form and you explained it really well. Keep it up! :-)

Good Stuff....try to be louder or better audio.

i cant see how your argument turns into 11/5..

[craiginboro]

surely you made an error when trying to make -11/5 to equal 0 you divided -11/5 by -5/11 which equal 4.84. wouldn't you either multiply by its reciprocal or divide n by itself -11/5 divided by -11/5 = 1 or -11/5 * -5/11=1

i hate how every two seconds the screen resets, ...no good!
