Step-by-step explanation:
The solutions for the 6th edition of "Linear Algebra and Its Applications" can typically be found in the instructor solutions manual. This manual contains the answers to the problems and exercises within the textbook. However, it is important to note that instructor solutions manuals are usually intended for instructors only, and may not be publicly available.
Another possible source for solutions is the publisher's website. Some publishers provide supplementary materials for their textbooks, including solutions manuals, that may be accessible to instructors or students with a valid account.
Additionally, university archives may have previous editions of the textbook, which could potentially have similar exercises and solutions. It's worth checking with your university library to see if they have any available resources.
