x+14\leq -12x+21
4x-7 ga -3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
x+14+12x\leq 21
12x ni ikki tarafga qo’shing.
13x+14\leq 21
13x ni olish uchun x va 12x ni birlashtirish.
13x\leq 21-14
Ikkala tarafdan 14 ni ayirish.
13x\leq 7
7 olish uchun 21 dan 14 ni ayirish.
x\leq \frac{7}{13}
Ikki tarafini 13 ga bo‘ling. 13 musbat bo‘lgani uchun, tengsizlik yo‘nalishi o‘zgarmaydi.
