3(2y-1)-2(y-4)=2(y+1)+9 eching

$$3 ( 2 y - 1 ) - 2 ( y - 4 ) = 2 ( y + 1 ) + 9$$

y uchun yechish

$$y=3$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

3 ga 2y-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$6y-3-2\left(y-4\right)=2\left(y+1\right)+9$$

-2 ga y-4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$6y-3-2y+8=2\left(y+1\right)+9$$

4y ni olish uchun 6y va -2y ni birlashtirish.

$$4y-3+8=2\left(y+1\right)+9$$

5 olish uchun -3 va 8'ni qo'shing.

$$4y+5=2\left(y+1\right)+9$$

2 ga y+1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$4y+5=2y+2+9$$

11 olish uchun 2 va 9'ni qo'shing.

$$4y+5=2y+11$$

Ikkala tarafdan 2y ni ayirish.

$$4y+5-2y=11$$

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

$$2y+5=11$$

Ikkala tarafdan 5 ni ayirish.

$$2y=11-5$$

6 olish uchun 11 dan 5 ni ayirish.

$$2y=6$$

Ikki tarafini 2 ga bo‘ling.

$$y=\frac{6}{2}$$

3 ni olish uchun 6 ni 2 ga bo‘ling.

$$y=3$$
