Ways to tell them apart:
Unsoluble refers to substances, like salt in water, that cannot dissolve.
Unsolvable is about problems or puzzles that can't be solved.
Think of soluble as involving dissolve for chemistry and solutions.
Remember solve involves finding the answer to a problem, so unsolvable means no answers can be found.
The prefix un- in both words indicates not, but what follows specifies the context: soluble for dissolving, solvable for resolving problems.
