3\left(2x-1\right)+3\left(x+2\right)=2\left(2x+7\right)
Tenglamaning ikkala tarafini 6 ga, 2,3 ning eng kichik karralisiga ko‘paytiring.
6x-3+3\left(x+2\right)=2\left(2x+7\right)
3 ga 2x-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
6x-3+3x+6=2\left(2x+7\right)
3 ga x+2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
9x-3+6=2\left(2x+7\right)
9x ni olish uchun 6x va 3x ni birlashtirish.
9x+3=2\left(2x+7\right)
3 olish uchun -3 va 6'ni qo'shing.
9x+3=4x+14
2 ga 2x+7 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
9x+3-4x=14
