"My question was answered."

Translation: 제 질문은 대답됐어요.

[CF00l]

제 質問은 對答됐어요.

대답하다 - to answer

대답되다 - to "get" answered (for lack of a better word to indicate present tense-ness)

대답됐다 - to be answered (means was answered in the past)

-되다 verbs are often passive forms of the corresponding -하다 verb.

It should be 제 질문이 대답됐어요

Both are fine, it will depend on the context (which is lacking here).
