8(s+17)leq4(3s+17)+20 eching

$$8 ( s + 17 ) \leq 4 ( 3 s + 17 ) + 20$$

s uchun yechish

$$s\geq 12$$

Yechim qadamlari

8 ga s+17 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$8s+136\leq 4\left(3s+17\right)+20$$

4 ga 3s+17 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$8s+136\leq 12s+68+20$$

88 olish uchun 68 va 20'ni qo'shing.

$$8s+136\leq 12s+88$$

Ikkala tarafdan 12s ni ayirish.

$$8s+136-12s\leq 88$$

-4s ni olish uchun 8s va -12s ni birlashtirish.

$$-4s+136\leq 88$$

Ikkala tarafdan 136 ni ayirish.

$$-4s\leq 88-136$$

-48 olish uchun 88 dan 136 ni ayirish.

$$-4s\leq -48$$

Ikki tarafini -4 ga bo‘ling. -4 manfiy boʻlgani uchun tengsizlikning yo‘nalishi o‘zgaradi.

$$s\geq \frac{-48}{-4}$$

12 ni olish uchun -48 ni -4 ga bo‘ling.

$$s\geq 12$$
