6\left(x+1\right)+4\left(x+3\right)=3\left(x+2\right)
Tenglamaning ikkala tarafini 12 ga, 2,3,4 ning eng kichik karralisiga ko‘paytiring.
6x+6+4\left(x+3\right)=3\left(x+2\right)
6 ga x+1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
6x+6+4x+12=3\left(x+2\right)
4 ga x+3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
10x+6+12=3\left(x+2\right)
10x ni olish uchun 6x va 4x ni birlashtirish.
10x+18=3\left(x+2\right)
18 olish uchun 6 va 12'ni qo'shing.
10x+18=3x+6
3 ga x+2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
10x+18-3x=6
Ikkala tarafdan 3x ni ayirish.
7x+18=6
7x ni olish uchun 10x va -3x ni birlashtirish.
7x=6-18
Ikkala tarafdan 18 ni ayirish.
7x=-12
-12 olish uchun 6 dan 18 ni ayirish.
x=\frac{-12}{7}
Ikki tarafini 7 ga bo‘ling.
x=-\frac{12}{7}
\frac{-12}{7} kasri manfiy belgini olib tashlash bilan -\frac{12}{7} sifatida qayta yozilishi mumkin.
