Using Gauss Jordan Elimination to determine the Inverse of a 3 x 3 Matrix

[@liamvorster7056]

how do you know what to do with each row?

[@molloymaths1092]

You need to end up with 1, 1, 1, in the diagonal and the rest zeros. How you get there may be different to the way I got there.

is it possible for someone to get a different set of numbers for the inverse by using different steps?

[@molloymaths1092]

No. A Matrix has only one inverse. Thanks for your question.

[@thedisciple7430]

Thanks for the video but when I solve questions, I get the left side to be an identity matrix but the inverse is somehow wrong. I do not know where I'm going wrong

[@molloymaths1092]

Can you send me a picture of what you did?

[@thedisciple7430]

sure. How can I get in contact with you?@@molloymaths1092
