30\left(5x+7\right)-15\left(3x+5\right)=24\left(4x+9\right)-40\left(x-9\right)
Tenglamaning ikkala tarafini 120 ga, 4,8,5,3 ning eng kichik karralisiga ko‘paytiring.
150x+210-15\left(3x+5\right)=24\left(4x+9\right)-40\left(x-9\right)
30 ga 5x+7 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
150x+210-45x-75=24\left(4x+9\right)-40\left(x-9\right)
-15 ga 3x+5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
105x+210-75=24\left(4x+9\right)-40\left(x-9\right)
105x ni olish uchun 150x va -45x ni birlashtirish.
105x+135=24\left(4x+9\right)-40\left(x-9\right)
135 olish uchun 210 dan 75 ni ayirish.
105x+135=96x+216-40\left(x-9\right)
24 ga 4x+9 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
105x+135=96x+216-40x+360
-40 ga x-9 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
105x+135=56x+216+360
56x ni olish uchun 96x va -40x ni birlashtirish.
105x+135=56x+576
576 olish uchun 216 va 360'ni qo'shing.
105x+135-56x=576
