Systems of Linear Equations with 3 Variables Using Elimination

[@MollyMcCandless]

So helpful! I'm taking a test on this tmrw, and only your video makes sense

[@MariosMathTutoring]

Glad it was helpful!

[@sampathkgopisetty5893]

Thank you this is very helpful

[@MASA-bk6ot]

THANK YOU SOO MUCH YOUR EXPLANATION IS THE BEST. IT'S EVEN BETTER THAN MY TEACHER'S EXPLANATION

[@MariosMathTutoring]

You're very welcome!

[@DusingizumuremyiFidele]

Iam happy to see the knowledge you. give

[@BridgetMulenga-o5z]

Best❤❤ I couldn't ask for more 😍

[@premjitnag4200]

Thank you sir

[@USBCord]

Very helpful, thank you!

[@MariosMathTutoring]

Glad it was helpful!

Is it normal that i find a different answer when i'm eliminating another variable? For example for the first one i got x= 5/3, y= 5/3 and z= 14/3 by eliminating first x

[@MariosMathTutoring]

You should always get the same answer regardless of which variable you choose to start with…maybe check your work again for an arithmetic error.

[@saweetieeee]

@@MariosMathTutoring yes i did it again i was wrong in a calcul !

[@ProtoMaxoid]

Not me solving this with linear algebra

[@Max587-yu1si]

Why when people do systems of 3 they always add but not subtract for the elimination method

[@MariosMathTutoring]

Good question…I often see students make mistakes when subtracting especially when there are negative numbers which is why I often just show the adding method.

You dont have to prove urself to your stepchildren mario youre a grown man
