If I wrote --> x= d,e for example, then am I right in thinking that all this says is that d and e are the only possible solutions and that I would need 'iff' to justify that these are the solutions?

If you are asked to solve an equation, you solve it! Solving it means finding all the values of, in this case, x that satisfy the equation. 'iff' is irrelevant.
Although, if I were your teacher, I would expect more than just " to indicate that d and e are meant to be the solutions. If you want to really shock your teacher, try writing full sentences: "x= d and x= e are the solutions to the equation "!

Yes, and one would of course achieve full marks but the reasoning would be faulty.
