Chiziqli tenglamalarni yechish bo'yicha qadamlar

2 ga 1-x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$2-2x-3\left(2x-1\right)-\left(1+x\right)=8$$

-3 ga 2x-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$2-2x-6x+3-\left(1+x\right)=8$$

-8x ni olish uchun -2x va -6x ni birlashtirish.

$$2-8x+3-\left(1+x\right)=8$$

5 olish uchun 2 va 3'ni qo'shing.

$$5-8x-\left(1+x\right)=8$$

1+x teskarisini topish uchun har birining teskarisini toping.

$$5-8x-1-x=8$$

4 olish uchun 5 dan 1 ni ayirish.

$$4-8x-x=8$$

-9x ni olish uchun -8x va -x ni birlashtirish.

$$4-9x=8$$

Ikkala tarafdan 4 ni ayirish.

$$-9x=8-4$$

4 olish uchun 8 dan 4 ni ayirish.

$$-9x=4$$

Ikki tarafini -9 ga bo‘ling.

$$x=\frac{4}{-9}$$

\frac{4}{-9} kasri manfiy belgini olib tashlash bilan -\frac{4}{9} sifatida qayta yozilishi mumkin.

$$x=-\frac{4}{9}$$
