Thanks a lot for the response, so basically start getting the inverse of the given matrix and get rid of the -1 on the left then and keep going, is that what you mean ?
Sounds logical, not sure why I never thought of it that way. Again thank you.
Homework Statement
Using the following information, find the matrix A
(I+2A)-1 =
[-1 2]
[4 5]
Homework Equations
AA-1 = I
The Attempt at a Solution
none. I have no idea how should I start. The inverse on the whole left side is driving me crazy.
