123(y+5)-(4y-8)=-2y+10 eching

$$123 ( y + 5 ) - ( 4 y - 8 ) = - 2 y + 10$$

y uchun yechish

$$y = -\frac{613}{121} = -5\frac{8}{121} \approx -5,066115702$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

123 ga y+5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$123y+615-\left(4y-8\right)=-2y+10$$

4y-8 teskarisini topish uchun har birining teskarisini toping.

$$123y+615-4y-\left(-8\right)=-2y+10$$

-8 ning teskarisi 8 ga teng.

$$123y+615-4y+8=-2y+10$$

119y ni olish uchun 123y va -4y ni birlashtirish.

$$119y+615+8=-2y+10$$

623 olish uchun 615 va 8'ni qo'shing.

$$119y+623=-2y+10$$

2y ni ikki tarafga qo’shing.

$$119y+623+2y=10$$

121y ni olish uchun 119y va 2y ni birlashtirish.

$$121y+623=10$$

Ikkala tarafdan 623 ni ayirish.

$$121y=10-623$$

-613 olish uchun 10 dan 623 ni ayirish.

$$121y=-613$$

Ikki tarafini 121 ga bo‘ling.

$$y=\frac{-613}{121}$$

\frac{-613}{121} kasri manfiy belgini olib tashlash bilan -\frac{613}{121} sifatida qayta yozilishi mumkin.

$$y=-\frac{613}{121}$$
