30b+53geq18b-83 eching

$$30 b + 53 \geq 18 b - 83$$

b uchun yechish

$$b\geq -\frac{34}{3}$$

Yechim qadamlari

Ikkala tarafdan 18b ni ayirish.

$$30b+53-18b\geq -83$$

12b ni olish uchun 30b va -18b ni birlashtirish.

$$12b+53\geq -83$$

Ikkala tarafdan 53 ni ayirish.

$$12b\geq -83-53$$

-136 olish uchun -83 dan 53 ni ayirish.

$$12b\geq -136$$

Ikki tarafini 12 ga bo‘ling. 12 >0 bo‘lganda, tengsizlikning yo‘nalishi o‘zgarmasdan qoladi.

$$b\geq \frac{-136}{12}$$

\frac{-136}{12} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$b\geq -\frac{34}{3}$$
