My first message to him is, "The answers should only be the answers to my questions. No other reasoning. Don't ask me questions. Are you ready to get my question?"

Yes, I am ready to answer your question.

Question:

  1. Prove that if a + b = c and c ≠ 0, then a = (c - b).
  2. Give real-life examples confirming this equality.

Response:

  1. Proof:

    If (a + b = c) and (c\neq 0), then to find (a), you can subtract (b) from both parts of the equation:

    [
    a + b - b = c - b \implies a = c - b
    ]

    Thus, ( a = c - b ).

  2. Real-life examples:

    • **- Finance: If you have 1,000 rubles ((c)) and you have spent 300 rubles ((and)), then you have (1,000 - 300 = 700) rubles ((a)) left.
    • Physics: If the total length of the stick is 50 cm ((c)), and one part is 20 cm long ((b)), then the other part is ( 50-20 = 30) cm long ((a)).
