Ex: Solve a System of Three Equations Using a Matrix Equation

This video explains how to solve a system of three linear equations with three unknowns using a matrix equation.

Great explanation! Clear and to the point... So many people tend to ramble on, but your video is understandable. Keep making videos!

This is a god type explanation dude, you helped me understand how to do it and I was able to complete my homework


Highly recommend you to any of my classmates

Hey thanks for posting this I have a semester test tomorrow for algebra 2 and this video helped me recall how to do this....Good thing you teach it better then my teacher.

[taylorlozoya]

This video saved my life, he explains it very well.

[MrTealdirtysenr]

This tutorial was so helpful im glad theres people like you!

[nadimmostafa]

Hope my teacher explained like this, and I'm paying him.

My inverse didn’t come out to decimals. I did A times B and got a three by one matrix. What do I do then because it also doesn’t equal the identity matrix, I used the matrix calculator I was given.

[MrMADman]

Holy crap, this has been a huge help. Thank you!

[alyattalla]

why all that if we could solve the equations directly by the calc

[traviscrashcarter]

that was quite helpful, you helped me cut about 5 minutes out of the FE exam. =)

[YoungFlav]

You did an extra step, that you didn't have to do but good video

[leoramos]

Very clear, and concise explanation. Thank you so much.

[Fries]

Thank you so much! I make so many mistakes during the process but this is so much easier.

[gavinmeyers]

this was useful but y dont u show how to invert 3x3

[pahouayang]

you explain better than my math professor who has taught for more than 20 years lol

[dampnickers]

Could you post the links in the video to show how to multiply the 3x3 and the 3x1 matrices, please?

[emscar_]

this video helped much! Thanks for putting this out

[thanishka]

what happens if the inverse does not exist? will X be equal to B or the whole equation becomes invalid??

[Legabis]

would this work on system of 4 linear equeatios with 3 unknowns?

[omendra]

Sir can u plZZ make a vdo for solution of three unknowns with two given equations by matrix mathod
