You can solve an equation with one unknown. You need two different equations for two unknowns, and so on.
This implies a binary distinction between 'known' and 'unknown'. But are there grades or shades of unknown? For instance, if you know that a variable is negative but not its magnitude, can that help solve an equation? If so, is there any field of study on what the different degrees of unknownness are?
