Since the parent mentioned my text, Linear Algebra, I'll note that it is Free, and comes with worked answers to all exercises, including proofs. And since other posters mention videos, I'll also note that there are videos (and the slides are available), along with a lab manual using Sage. https://hefferon.net/linearalgebra/index.html

:-) I should say that my college, a SLAC, has kindly supported the work for many years, including tolerating the download traffic.
