Answer 3

I'm sorry, but I'm not able to understand the statement you provided. It appears to be an equation, but it is not clear what you're asking or what you mean by "дам 20бал" (which translates to "I'll give 20 points" in English).

If you could please provide more information or clarify your question, I'll do my best to assist you.
