3+2(n-1)=13 eching

$$3 + 2 ( n - 1 ) = 13$$

n uchun yechish

$$n=6$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

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

$$3+2n-2=13$$

1 olish uchun 3 dan 2 ni ayirish.

$$1+2n=13$$

Ikkala tarafdan 1 ni ayirish.

$$2n=13-1$$

12 olish uchun 13 dan 1 ni ayirish.

$$2n=12$$

Ikki tarafini 2 ga bo‘ling.

$$n=\frac{12}{2}$$

6 ni olish uchun 12 ni 2 ga bo‘ling.

$$n=6$$
