Chiziqli tenglamalarni yechish bo'yicha qadamlar

4 ga 7y+2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$28y+8-9\left(5-y\right)=-43$$

-9 ga 5-y ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$28y+8-45+9y=-43$$

-37 olish uchun 8 dan 45 ni ayirish.

$$28y-37+9y=-43$$

37y ni olish uchun 28y va 9y ni birlashtirish.

$$37y-37=-43$$

37 ni ikki tarafga qo’shing.

$$37y=-43+37$$

-6 olish uchun -43 va 37'ni qo'shing.

$$37y=-6$$

Ikki tarafini 37 ga bo‘ling.

$$y=\frac{-6}{37}$$

\frac{-6}{37} kasri manfiy belgini olib tashlash bilan -\frac{6}{37} sifatida qayta yozilishi mumkin.

$$y=-\frac{6}{37}$$
