3(-5+c)-2(c-4)=2-7c-1 eching

$$3 ( - 5 + c ) - 2 ( c - 4 ) = 2 - 7 c - 1$$

c uchun yechish

$$c=1$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

3 ga -5+c ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$-15+3c-2\left(c-4\right)=2-7c-1$$

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

$$-15+3c-2c+8=2-7c-1$$

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

$$-15+c+8=2-7c-1$$

-7 olish uchun -15 va 8'ni qo'shing.

$$-7+c=2-7c-1$$

1 olish uchun 2 dan 1 ni ayirish.

$$-7+c=1-7c$$

7c ni ikki tarafga qo’shing.

$$-7+c+7c=1$$

8c ni olish uchun c va 7c ni birlashtirish.

$$-7+8c=1$$

7 ni ikki tarafga qo’shing.

$$8c=1+7$$

8 olish uchun 1 va 7'ni qo'shing.

$$8c=8$$

Ikki tarafini 8 ga bo‘ling.

$$c=\frac{8}{8}$$

1 ni olish uchun 8 ni 8 ga bo‘ling.

$$c=1$$
