7(y-3)=2(y-9)+2y eching

$$7 ( y - 3 ) = 2 ( y - 9 ) + 2 y$$

y uchun yechish

$$y=1$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

7 ga y-3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$7y-21=2\left(y-9\right)+2y$$

2 ga y-9 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$7y-21=2y-18+2y$$

4y ni olish uchun 2y va 2y ni birlashtirish.

$$7y-21=4y-18$$

Ikkala tarafdan 4y ni ayirish.

$$7y-21-4y=-18$$

3y ni olish uchun 7y va -4y ni birlashtirish.

$$3y-21=-18$$

21 ni ikki tarafga qo’shing.

$$3y=-18+21$$

3 olish uchun -18 va 21'ni qo'shing.

$$3y=3$$

Ikki tarafini 3 ga bo‘ling.

$$y=\frac{3}{3}$$

1 ni olish uchun 3 ni 3 ga bo‘ling.

$$y=1$$
