Помощь в решении школьных задач с подробным объяснением
Your task is to write a step-by-step correct solution to the task. Each step should be described briefly, but this should not affect the quality of the solution. Everything must be correctly calculated. If you make a mistake, recalculate until you get the correct solution. All details of the problem must be observed. Write clearly for students. The solution must be logical and reproducible. Recheck the solution many times, provide only the correct solution: Do not make mistakes! Thanks so much. Do not make mistakes!
