8(y+4)-2(y-1)=70-3y eching

$$8 ( y + 4 ) - 2 ( y - 1 ) = 70 - 3 y$$

y uchun yechish

$$y=4$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

8 ga y+4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$8y+32-2\left(y-1\right)=70-3y$$

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

$$8y+32-2y+2=70-3y$$

6y ni olish uchun 8y va -2y ni birlashtirish.

$$6y+32+2=70-3y$$

34 olish uchun 32 va 2'ni qo'shing.

$$6y+34=70-3y$$

3y ni ikki tarafga qo’shing.

$$6y+34+3y=70$$

9y ni olish uchun 6y va 3y ni birlashtirish.

$$9y+34=70$$

Ikkala tarafdan 34 ni ayirish.

$$9y=70-34$$

36 olish uchun 70 dan 34 ni ayirish.

$$9y=36$$

Ikki tarafini 9 ga bo‘ling.

$$y=\frac{36}{9}$$

4 ni olish uchun 36 ni 9 ga bo‘ling.

$$y=4$$
