Nice, quick, clear demo...thanks,

[@RobSummers993]

Dude you are the MAN! Gracias

[@naotanoguchi8066]

if you're new to this like me, and get a syntax error, there is two different buttons for minus and negative

[@btmillion2813]

Naota Noguchi thanks a lot! I didn’t realize that.

[@karenbonnetti-ramirez6264]

Thank you!

[@SupremeKamina]

Thank you soooo much for this i've been searching for this for 3 hours and i didnt find anything thank realy you saved me

[@berenicereyes617]

thanks you helped me in my equations exam☺🧡

[@KwuOats]

gonna use it on the SAT wish me luck

[@star7226]

Thank you

[@jansirkia3809]

Thanks!

[@cr1mc0rechannel83]

Thank you very much! 👍🏻

[@bastienclarke1810]

Super! Thanks! :)

[@Noah-ow3te]

If you are having non-algebraic variable in expression error, clear variables using 2nd+6 then f1 to clear memory!

[@cr1mc0rechannel83]

THANK YOU VERY MUCH, I follow 2nd + 6 then f1, RAM -> All RAM

[@juanromero4934]

muchas gracias buen hombre

[@karenbonnetti-ramirez6264]

Awesome! TY :)

[@auronthas]

use Matrix is simple for simultaneous equations

[@naderhumood1199]

Terrific keep it up. Thank you very much.

[@karolinacgutierrez991]

Thank you!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!🎉🎉🎉🎉

[@oxqa]

Thank you 😎👍🏽

[@VinamasSiros]

you saved me have a like my savior

[@HolyHusky]

I entered this problem Exactly the way you did and i get “non algebraic variable in expression” any help?

[@victorvivanco8922]

Me too, please help!!!

[@rafahaahmed]

I have been trying for 30 min, same problem

[@jesuscoronado8721]

I know that this was 5 months ago but maybe could help someone else. Do this on home: F4 4 (name of your variable, in my case x) enter Now try again. The problem is gone.

[@ThePooponthewindow]

@@jesuscoronado8721 THANK YOU

[@jorismarek2391]

Thanks

[@karolinacgutierrez991]

Do u have tutorial to find the inverse equation in the ti89 ?

[@another-learner8677]

Would this work when you have imaginary numbers in equations?

[@issemohamed2657]

Just change the mode to complex mode

[@gamingqueen2478]

says argument error

[@Shedir]

F6, 1 (clear a-z)

[@strahinjajeremic3706]

Hello. Nice video! Could you tell us what is this emulator you are using in this video?

[@fantasan8540]

Any way to do this on the ti-84?

[@alejandrocaballero8225]

[@danielwood9471]

is there a way to program this process to make it simpler to type in? You know engineers are lazy which is why i'm asking you instead of googling it or figuring it out for myself.

[@iangiovaanni]

My TI-89 give me the solutions depending the same variables that I´m looking for. Does anyone know why? I solved the system by hand and they give me the correct solutions

[@Diamond_Hanz]

Matrix

[@floridian2023]

W.O.W.

[@mar56cos]

do you need to have the 3 variables in each of he equations? or can one eq only have 2 variables?

[@mar56cos]

Just answered my own question. lol, The answer is yes, so If one Equation only has 2 variables add what ever variable is missing with a 0, for ex. 0x + 3Y-2Z =9, otherwise it might give you an error.
