Translation from two languages

I have a text document in two languages, how can I translate the text into another language?
For example, text in German and English translate into Russian.

This option is not correct

@Assel_Madrakhimova Have you tried with Google translate activities?

whether with 1 language runs smoothly?

I tried with one language, I get an error:

Translate: The remote server returned an error: (407) Proxy Authentication Required.

With google i need to enter keys, I’m looking for an easier metod
