Ex: Solve the Matrix Equation AX=B (3x3)

This video explains how to solve a matrix equation in the form AX=B.

[@mycousins896]

can you interchange row 1 with row 3? and if you do that, should you also change the row 1 of identity matrix with row 3 in finding A^-1?

[@lewisjones284]

Super helpful writing the proof at the beginning, thank you!

[@rajbhattacharya8114]

Just can't understand the process to find the A^-1... Pls explain that part🙂

[@tempestandacomputer6951]

Gotta find a video for that!
But really, you just have to set A equal to an identity matrix and perform row operations until A looks like an identity matrix. When that is achieved, what was once identity matrix is now your A inverse:)

Awesome! Short and sweet video. Loved it.

got perfect on this question on the midterm thanks to you.

[@deidera8325]

thanks, it helped a lot !

[@isaamaral]

could you help me with this: If A and B are square matrices of the same order n and invertible, solve the matrix equations: a) XAB = A b) overline XA - B = A (AX)-1= B

[@davidll4334]

in the first minute, you can make a simple replacement? like ax=b then x = b/a and that's it?

Thanks for helping ,it helped lot of , suddenly ,I find you channel , you clear my all doubt thanks again ,we will hopefull to you

[@aroabeltran5698]

Thank you, saved my day

[@clarebellcazon6265]

Exelente.!!Perfect!!..

[@karizma5521]

Is there a way to solve this when A is not invertable or is there no solution?

Helpful, thanks

[@Mathispower4u]

I am glad. Thank you for the comment!

[@peterwong246]

Thx

[@Keitumetsemulaudzi]

thanks ey.

[@Duckerton]

Have absolutely no idea how you got those numbers for your inverse. Gotta use the ole calculator
