2n-2(x+4)=5x+6 eching

$$2 n - 2 ( x + 4 ) = 5 x + 6$$

n uchun yechish

$$n=\frac{7\left(x+2\right)}{2}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

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

$$2n-2x-8=5x+6$$

2x ni ikki tarafga qo’shing.

$$2n-8=5x+6+2x$$

7x ni olish uchun 5x va 2x ni birlashtirish.

$$2n-8=7x+6$$

8 ni ikki tarafga qo’shing.

$$2n=7x+6+8$$

14 olish uchun 6 va 8'ni qo'shing.

$$2n=7x+14$$

Ikki tarafini 2 ga bo‘ling.

$$\frac{2n}{2}=\frac{7x+14}{2}$$

2 ga bo'lish 2 ga ko'paytirishni bekor qiladi.

$$n=\frac{7x+14}{2}$$

14+7x ni 2 ga bo'lish.

$$n=\frac{7x}{2}+7$$

x uchun yechish

$$x=\frac{2\left(n-7\right)}{7}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

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

$$2n-2x-8=5x+6$$

Ikkala tarafdan 5x ni ayirish.

$$2n-2x-8-5x=6$$

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

$$2n-7x-8=6$$

Ikkala tarafdan 2n ni ayirish.

$$-7x-8=6-2n$$

8 ni ikki tarafga qo’shing.

$$-7x=6-2n+8$$

14 olish uchun 6 va 8'ni qo'shing.

$$-7x=14-2n$$

Ikki tarafini -7 ga bo‘ling.

$$\frac{-7x}{-7}=\frac{14-2n}{-7}$$

-7 ga bo'lish -7 ga ko'paytirishni bekor qiladi.

$$x=\frac{14-2n}{-7}$$

14-2n ni -7 ga bo'lish.

$$x=\frac{2n}{7}-2$$
