3n+6/n-4=2 eching

$$\frac{3n+6}{n-4}=2$$

n uchun yechish

$$n=-14$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

n qiymati 4 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini n-4 ga ko'paytirish.

$$3n+6=2\left(n-4\right)$$

2 ga n-4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$3n+6=2n-8$$

Ikkala tarafdan 2n ni ayirish.

$$3n+6-2n=-8$$

n ni olish uchun 3n va -2n ni birlashtirish.

$$n+6=-8$$

Ikkala tarafdan 6 ni ayirish.

$$n=-8-6$$

-14 olish uchun -8 dan 6 ni ayirish.

$$n=-14$$
