I don’t think I know of any resource where you can get your answers of basic algebra question checked within hours. There however are a couple of websites which do offer assistance, but one has to wait for at least 24 hours before getting some response.What I know for sure is that, this program called Algebra Buster, that I used during my college career was really good and I was quite happy with it. It almost gives the type of solutions you need.
Welcome aboard friend. This subject is very appealing, but you need to know your basics and techniques first. Algebra Buster has guided me a lot in my course. Do give it a try and it will work for you too.
