30-6\times 2x+3\left(2+x\right)=2\left(x-4\right)
Tenglamaning ikkala tarafini 30 ga, 5,10,15 ning eng kichik karralisiga ko‘paytiring.
30-12x+3\left(2+x\right)=2\left(x-4\right)
-12 hosil qilish uchun -6 va 2 ni ko'paytirish.
30-12x+6+3x=2\left(x-4\right)
3 ga 2+x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
36-12x+3x=2\left(x-4\right)
36 olish uchun 30 va 6'ni qo'shing.
36-9x=2\left(x-4\right)
-9x ni olish uchun -12x va 3x ni birlashtirish.
36-9x=2x-8
2 ga x-4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
36-9x-2x=-8
Ikkala tarafdan 2x ni ayirish.
36-11x=-8
-11x ni olish uchun -9x va -2x ni birlashtirish.
-11x=-8-36
Ikkala tarafdan 36 ni ayirish.
-11x=-44
