Yechim qadamlari

Ikkala tarafdan 80a ni ayirish.

$$60a+64-80a\geq -92$$

-20a ni olish uchun 60a va -80a ni birlashtirish.

$$-20a+64\geq -92$$

$$-20a\geq -92-64$$

-156 olish uchun -92 dan 64 ni ayirish.

$$-20a\geq -156$$

Ikki tarafini -20 ga bo‘ling. -20 manfiy boʻlgani uchun tengsizlikning yo‘nalishi o‘zgaradi.

$$a\leq \frac{-156}{-20}$$

\frac{-156}{-20} ulushini -4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
