$$60000+150a-150000\geq 75000$$

-90000 olish uchun 60000 dan 150000 ni ayirish.

$$-90000+150a\geq 75000$$

90000 ni ikki tarafga qo’shing.

$$150a\geq 75000+90000$$

165000 olish uchun 75000 va 90000'ni qo'shing.

$$150a\geq 165000$$

Ikki tarafini 150 ga bo‘ling. 150 musbat bo‘lgani uchun, tengsizlik yo‘nalishi o‘zgarmaydi.

$$a\geq \frac{165000}{150}$$

1100 ni olish uchun 165000 ni 150 ga bo‘ling.

$$a\geq 1100$$
