80000-4000x+2500\left(30+2x\right)<16000
4000 ga 20-x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
80000-4000x+75000+5000x<16000
2500 ga 30+2x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
155000-4000x+5000x<16000
155000 olish uchun 80000 va 75000'ni qo'shing.
155000+1000x<16000
1000x ni olish uchun -4000x va 5000x ni birlashtirish.
1000x<16000-155000
Ikkala tarafdan 155000 ni ayirish.
1000x<-139000
-139000 olish uchun 16000 dan 155000 ni ayirish.
x<\frac{-139000}{1000}
Ikki tarafini 1000 ga bo‘ling. 1000 musbat bo‘lgani uchun, tengsizlik yo‘nalishi o‘zgarmaydi.
x<-139
-139 ni olish uchun -139000 ni 1000 ga bo‘ling.
