"I come with my two parents."
Translation:Ich komme mit meinen beiden Eltern.
It might be "meine" instead. I don't know if you have to inflect "mein" into the dative since you've already inflected beide, the word right before, into the dative. "Meine" would be nominative plural, matching Eltern.
Of course, you still produced the German "I come with both my parents" when asked to produce the German "I come with my two parents."
