-4(8-y)geq7(y-2)-y eching

$$- 4 ( 8 - y ) \geq 7 ( y - 2 ) - y$$

y uchun yechish

$$y\leq -9$$

Yechim qadamlari

-4 ga 8-y ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$-32+4y\geq 7\left(y-2\right)-y$$

7 ga y-2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$-32+4y\geq 7y-14-y$$

6y ni olish uchun 7y va -y ni birlashtirish.

$$-32+4y\geq 6y-14$$

Ikkala tarafdan 6y ni ayirish.

$$-32+4y-6y\geq -14$$

-2y ni olish uchun 4y va -6y ni birlashtirish.

$$-32-2y\geq -14$$

32 ni ikki tarafga qo’shing.

$$-2y\geq -14+32$$

18 olish uchun -14 va 32'ni qo'shing.

$$-2y\geq 18$$

Ikki tarafini -2 ga bo‘ling. -2 manfiy boʻlgani uchun tengsizlikning yo‘nalishi o‘zgaradi.

$$y\leq \frac{18}{-2}$$

-9 ni olish uchun 18 ni -2 ga bo‘ling.

$$y\leq -9$$
