18-ygeq4(y-3) eching

$$18 - y \geq 4 ( y - 3 )$$

y uchun yechish

$$y\leq 6$$

Yechim qadamlari

4 ga y-3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$18-y\geq 4y-12$$

Ikkala tarafdan 4y ni ayirish.

$$18-y-4y\geq -12$$

-5y ni olish uchun -y va -4y ni birlashtirish.

$$18-5y\geq -12$$

Ikkala tarafdan 18 ni ayirish.

$$-5y\geq -12-18$$

-30 olish uchun -12 dan 18 ni ayirish.

$$-5y\geq -30$$

Ikki tarafini -5 ga bo‘ling. -5 manfiy boʻlgani uchun tengsizlikning yo‘nalishi o‘zgaradi.

$$y\leq \frac{-30}{-5}$$

6 ni olish uchun -30 ni -5 ga bo‘ling.

$$y\leq 6$$
