n uchun yechish

$$n=-15$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

9 ga n+3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$9n+27=7n-3$$

Ikkala tarafdan 7n ni ayirish.

$$9n+27-7n=-3$$

2n ni olish uchun 9n va -7n ni birlashtirish.

$$2n+27=-3$$

Ikkala tarafdan 27 ni ayirish.

$$2n=-3-27$$

-30 olish uchun -3 dan 27 ni ayirish.

$$2n=-30$$

Ikki tarafini 2 ga bo‘ling.

$$n=\frac{-30}{2}$$

-15 ni olish uchun -30 ni 2 ga bo‘ling.

$$n=-15$$
