3c+30=15c+6
3 ga 5c+2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
3c+30-15c=6
Ikkala tarafdan 15c ni ayirish.
-12c+30=6
-12c ni olish uchun 3c va -15c ni birlashtirish.
-12c=6-30
Ikkala tarafdan 30 ni ayirish.
-12c=-24
-24 olish uchun 6 dan 30 ni ayirish.
c=\frac{-24}{-12}
Ikki tarafini -12 ga bo‘ling.
c=2
2 ni olish uchun -24 ni -12 ga bo‘ling.
