Differential Equations and Linear Algebra (2nd Edition)
C. Henry Edwards, David E. Penney
As with most "official" solutions manuals, this one is pretty much junk. It contains "full" solutions to only odd problems, and those "fully" solutions generally skip steps, assume that you've already mastered the concepts (which you obviously haven't at this level), and on occasion, don't even solve problems the way the book recommends. Instead of purchasing a solutions manual for this DiffieEq book, I'd just recommend using Cramster. For free they've got AWESOME solutions to all odds which clearly explain what's going on, and for ten bucks a month they got you covered on all the evens as well. For some reason this site is not as well-known as it should be, but save yourself some money and headaches and check it out before buying crappy solutions manuals. Just Google "Cramster" and you'll be set!!
