30b+53-18b>-83
Ikkala tarafdan 18b ni ayirish.
12b+53>-83
12b ni olish uchun 30b va -18b ni birlashtirish.
12b>-83-53
Ikkala tarafdan 53 ni ayirish.
12b>-136
-136 olish uchun -83 dan 53 ni ayirish.
b>\frac{-136}{12}
Ikki tarafini 12 ga bo‘ling. 12 musbat bo‘lgani uchun, tengsizlik yo‘nalishi o‘zgarmaydi.
b>-\frac{34}{3}
\frac{-136}{12} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
