please find time to do this math problem I'll be very grateful to you.
please do it step by step because i am studying for my test.

Hi,

that's not how it works here! We don't do your homework. You have to show some kind of attempt! Where are you stuck?

here are my attempts

Man, for the matrix task I see that you don't understand the basic concepts.
adjA is matrix not scalar .
X is 3x3 matrix not scalar.

1) Hint:





This would mean that is the inverse of

So to find or

tnx for response

Is this looks like something?

I am afraid that it isn't the correct answer. What for you found A^(-1)?

Also you did some miscalculations in B^(-1).

Just work step by step.

First find B^(-1), then B^(-1)-2I then (B^(-1)-2I)^(-1) and finally A-(B^(-1)-2I)^(-1)

xexe I don't have smart answer to the first question
I found errors in B^(-1) and thanks to you I completed the task
Thank you
If you or someone else have a solution for my other problem please help
or if you have some good link for a similar done example?!
