3(x-4)-(8-x)=12 eching

$$3(x-4)-(8-x)=12$$

x uchun yechish

$$x=8$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

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

$$3x-12-\left(8-x\right)=12$$

8-x teskarisini topish uchun har birining teskarisini toping.

$$3x-12-8-\left(-x\right)=12$$

-x ning teskarisi x ga teng.

$$3x-12-8+x=12$$

-20 olish uchun -12 dan 8 ni ayirish.

$$3x-20+x=12$$

4x ni olish uchun 3x va x ni birlashtirish.

$$4x-20=12$$

20 ni ikki tarafga qo’shing.

$$4x=12+20$$

32 olish uchun 12 va 20'ni qo'shing.

$$4x=32$$

Ikki tarafini 4 ga bo‘ling.

$$x=\frac{32}{4}$$

8 ni olish uchun 32 ni 4 ga bo‘ling.

$$x=8$$
