in English

Sure — I can help. Please paste the task text or upload the image. Since Subject and Class aren’t specified, I’ll tailor the explanation to a middle-school level. The solution will be in English.

What you’ll get:

• A clear, step-by-step solution in English.
• Explanations of each step and the reasoning.
• Final answer with a quick check (where appropriate).

If you want me to translate from Russian or another language, tell me and I’ll translate to English and then solve.

Please share the problem.
