$$4 ( 6 u + 9 ) \geq 19 u + 11$$

u uchun yechish

$$u\geq -5$$

Yechim qadamlari

4 ga 6u+9 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$24u+36\geq 19u+11$$

Ikkala tarafdan 19u ni ayirish.

$$24u+36-19u\geq 11$$

5u ni olish uchun 24u va -19u ni birlashtirish.

$$5u+36\geq 11$$

Ikkala tarafdan 36 ni ayirish.

$$5u\geq 11-36$$

-25 olish uchun 11 dan 36 ni ayirish.

$$5u\geq -25$$

Ikki tarafini 5 ga bo‘ling. 5 musbat bo‘lgani uchun, tengsizlik yo‘nalishi o‘zgarmaydi.

$$u\geq \frac{-25}{5}$$

-5 ni olish uchun -25 ni 5 ga bo‘ling.

$$u\geq -5$$
