2\left(k+1\right)+6=3\left(3k+1\right)
Tenglamaning ikkala tarafini 6 ga, 3,2 ning eng kichik karralisiga ko‘paytiring.
2k+2+6=3\left(3k+1\right)
2 ga k+1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
2k+8=3\left(3k+1\right)
8 olish uchun 2 va 6'ni qo'shing.
2k+8=9k+3
3 ga 3k+1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
2k+8-9k=3
Ikkala tarafdan 9k ni ayirish.
-7k+8=3
-7k ni olish uchun 2k va -9k ni birlashtirish.
-7k=3-8
Ikkala tarafdan 8 ni ayirish.
-7k=-5
-5 olish uchun 3 dan 8 ni ayirish.
k=\frac{-5}{-7}
Ikki tarafini -7 ga bo‘ling.
k=\frac{5}{7}
Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-5}{-7} kasrini \frac{5}{7} ga soddalashtirish mumkin.
