7\left(400+9y\right)-55y=4400
Tenglamaning ikkala tarafini 11 ga ko'paytirish.
2800+63y-55y=4400
7 ga 400+9y ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
2800+8y=4400
8y ni olish uchun 63y va -55y ni birlashtirish.
8y=4400-2800
Ikkala tarafdan 2800 ni ayirish.
8y=1600
1600 olish uchun 4400 dan 2800 ni ayirish.
y=\frac{1600}{8}
Ikki tarafini 8 ga bo‘ling.
y=200
200 ni olish uchun 1600 ni 8 ga bo‘ling.
