Homework Statement
My textbook has no answers so I was wondering if someone could let me know if I'm right.
The question: A and B are m x n matrices.
Let A = I. Find when B = A.
Homework Equations
The Attempt at a Solution
What I did seems too easy:
If B ~ A, then A ~ B (this is just a property of similarity)
Since A = I, we can sub in for A
So B = A
Did I just argue myself in circles?
