n+2/7-n+3/2=-5 eching

$$\frac { n + 2 } { 7 } - \frac { n + 3 } { 2 } = - 5$$

n uchun yechish

$$n = \frac{53}{5} = 10\frac{3}{5} = 10,6$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tenglamaning ikkala tarafini 14 ga, 7,2 ning eng kichik karralisiga ko‘paytiring.

$$2\left(n+2\right)-7\left(n+3\right)=-70$$

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

$$2n+4-7\left(n+3\right)=-70$$

-7 ga n+3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$2n+4-7n-21=-70$$

-5n ni olish uchun 2n va -7n ni birlashtirish.

$$-5n+4-21=-70$$

-17 olish uchun 4 dan 21 ni ayirish.

$$-5n-17=-70$$

17 ni ikki tarafga qo’shing.

$$-5n=-70+17$$

-53 olish uchun -70 va 17'ni qo'shing.

$$-5n=-53$$

Ikki tarafini -5 ga bo‘ling.

$$n=\frac{-53}{-5}$$

Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-53}{-5} kasrini \frac{53}{5} ga soddalashtirish mumkin.

$$n=\frac{53}{5}$$
