-67b+6-9b\leq 43
Ikkala tarafdan 9b ni ayirish.
-76b+6\leq 43
-76b ni olish uchun -67b va -9b ni birlashtirish.
-76b\leq 43-6
Ikkala tarafdan 6 ni ayirish.
-76b\leq 37
37 olish uchun 43 dan 6 ni ayirish.
b\geq -\frac{37}{76}
Ikki tarafini -76 ga bo‘ling. -76 <0 bo‘lganda, tengsizlikning yo‘nalishi o‘zgargan bo‘ladi.
