Hi
In your question you asked what the difference is between "solve" and "resolve".
Both verbs have meanings that overlap and those that don't. The word "solve" is confined to "finding a solution". One can solve a problem, but one can also solve a puzzle, solve a mathematics equation, etc. One does not usually resolve puzzles or equations. One can also resolve a problem. This can mean finding a solution, but it usually extends beyond that -- to making the problem go away.
Hope this answers your question satisfactorily.
