Answer 2

Savolni tushunmadim, lekin sizga yordam bera olishim kerak. Siz quyidagi savolni berayotgan ekspresiyalarni qanday ochish kerakligini aytmoqchi bo'lsangiz, menga yordam bering:

Berilgan ifadalar:

a) 9. (5x + 2); b) 7 (9x - 11); c) 5. (7c + 3); d) 5. (10 + 7x); e) (3y - 5) 3; f) (9 - 5y) . 8.

Agar siz barcha usullarni qo'llab-quvvatlashga qaror qilgansangiz, ularni yana hamoshaza ifodalarga ajratib, ulardan ba'zi odamlar uchun tushunarliroq bo'lishini ta'minlay olasiz:

a) 9 * (5x + 2) = 45x + 18; b) 7 * (9x - 11) = 63x - 77; c) 5 * (7c + 3) = 35c + 15; d) 5 * (10 + 7x) = 50 + 35x; e) (3y - 5) * 3 = 9y - 15; f) (9 - 5y) * 8 = 72 - 40y.

Agar men boshqa tafsilotlarga ega bo'lsam, yoki agar savolingizni boshqa usulda tushuntirishim kerak bo'lsa, iltimos, ko'rsating.
