\frac{1}{3}x+\frac{1}{3}\left(-6\right)<x+8
\frac{1}{3} ga x-6 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
\frac{1}{3}x+\frac{-6}{3}<x+8
\frac{-6}{3} hosil qilish uchun \frac{1}{3} va -6 ni ko'paytirish.
\frac{1}{3}x-2<x+8
-2 ni olish uchun -6 ni 3 ga bo‘ling.
\frac{1}{3}x-2-x<8
Ikkala tarafdan x ni ayirish.
-\frac{2}{3}x-2<8
-\frac{2}{3}x ni olish uchun \frac{1}{3}x va -x ni birlashtirish.
-\frac{2}{3}x<8+2
2 ni ikki tarafga qo’shing.
-\frac{2}{3}x<10
10 olish uchun 8 va 2'ni qo'shing.
x>10\left(-\frac{3}{2}\right)
Ikki tarafini -\frac{3}{2} va teskari kasri -\frac{2}{3} ga ko‘paytiring. -\frac{2}{3} manfiy boʻlgani uchun tengsizlikning yo‘nalishi o‘zgaradi.
x>\frac{10\left(-3\right)}{2}
10\left(-\frac{3}{2}\right) ni yagona kasrga aylantiring.
x>\frac{-30}{2}
-30 hosil qilish uchun 10 va -3 ni ko'paytirish.
x>-15
-15 ni olish uchun -30 ni 2 ga bo‘ling.
