30x-5\left(2-x\right)=6\left(x+2\right)
Tenglamaning ikkala tarafini 30 ga, 6,5 ning eng kichik karralisiga ko‘paytiring.
30x-10+5x=6\left(x+2\right)
-5 ga 2-x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
35x-10=6\left(x+2\right)
35x ni olish uchun 30x va 5x ni birlashtirish.
35x-10=6x+12
6 ga x+2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
35x-10-6x=12
Ikkala tarafdan 6x ni ayirish.
29x-10=12
