The document contains a set of matrix-related problems from an assignment at Graphic Era University. The questions cover various topics such as elementary row transformations, rank of matrices, solving systems of linear equations, eigenvalues and eigenvectors, and verifying the Cayley-Hamilton theorem.

Would you like me to solve a specific problem from the assignment? I can provide detailed solutions and explanations for any of them.

Here are five related questions you could consider next:

1. How can elementary row transformations be used to find the inverse of a matrix?
2. What is the method to reduce a matrix to normal form and find its rank?
3. How can we determine if a system of equations has a unique, no, or infinite solution?
4. How do eigenvalues relate to the diagonalization of a matrix?
5. What is the Cayley-Hamilton theorem and how can it be verified?

Tip: When solving for the inverse of a matrix using row transformations, always aim to form the identity matrix on one side while transforming the other side into the inverse.
