TI-84 Tutorial - Solving for 3 Variables using the RREF Feature (in Matrix Menu) 

I wondered why mesh analysis of circuits is so popular over other methods, because solving multivariable equations is painstaking! The secret I didn't know is that these guys aren't doing the heavy lifting, they use keystrokes and the answer pops out.

extremely helpful! i can stop hemhorraging sanity now!

Thank you so much! This was a really well paced guide.

my goodness this was an amazing explanation. thank you so much

Great skills video. Thank you. You are so easy to understand.

Thank you! helped so much!

I did exactly what you did but for some odd reason it doesn't show the answers just the row of 1's. Do you know how to solve this

Can you use this to solve Lagrange equations?

Thanks a ton man

great video

Thanks 😊

I wish I knew this in 8th grade... everything I’ve done in math was just to waste my time. I’ve been using the same calculator, but doing the same math problems just building up to me learning this in college.

i love you thank you

Bro thank u sm

Thanks!

thanks

thank you soooo much for this
