If it is a gel back carpet then the backing has quite likely distorted. A secondary backed carpet might have delaminated. Need to know what solvent and what backing. As said before there are many different solvents with different properties and uses, you need to know what to use on what.
Saying ' a solvent' is being very vague.
If the backing or floor has been contaminated with any oil based solution then you will have difficulty in getting any adhesion anyways.
