3500a+1200a+1200\leq 20000
1200 ga a+1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
4700a+1200\leq 20000
4700a ni olish uchun 3500a va 1200a ni birlashtirish.
4700a\leq 20000-1200
Ikkala tarafdan 1200 ni ayirish.
4700a\leq 18800
18800 olish uchun 20000 dan 1200 ni ayirish.
a\leq \frac{18800}{4700}
Ikki tarafini 4700 ga bo‘ling. 4700 musbat bo‘lgani uchun, tengsizlik yo‘nalishi o‘zgarmaydi.
a\leq 4
4 ni olish uchun 18800 ni 4700 ga bo‘ling.
