Suppose I wanted to say to someone, "Can you solve this question?" According to my Memrise app and some Google results, this is the model sentence:

> 
> (1) この問題が**解けます**か。
> 
> 
> 

Since potential ("can") is involved, shouldn't the Japanese sentence be:

> 
> (2) この問題が**解けられます**か。
> 
> 
> 

Perhaps the literal meaning of (1) is "Will this question be in a solved state?", similar to ドアがしまりますか。*Is the (automatic, maybe) door going to be closed?* Perhaps this literal meaning is widely taken to mean "Can you solve this question?"

I've asked a [similar question about dictionary form vs potential form](https://japanese.stackexchange.com/questions/30823/%E3%81%A8%E3%81%BE%E3%82%89%E3%81%AA%E3%81%84-in-one-punch-man-op-meaning-%E3%81%A8%E3%81%BE%E3%82%8C%E3%81%AA%E3%81%84-negative-potential), but due to the limited context of that question, I would like to know **if the dictionary form can be used as the potential form in general**.
