Chiziqli tenglamalarni yechish bo'yicha qadamlar

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

$$4+2x-6-7x=13x-\left(1+4x\right)$$

-2 olish uchun 4 dan 6 ni ayirish.

$$-2+2x-7x=13x-\left(1+4x\right)$$

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

$$-2-5x=13x-\left(1+4x\right)$$

1+4x teskarisini topish uchun har birining teskarisini toping.

$$-2-5x=13x-1-4x$$

9x ni olish uchun 13x va -4x ni birlashtirish.

$$-2-5x=9x-1$$

Ikkala tarafdan 9x ni ayirish.

$$-2-5x-9x=-1$$

-14x ni olish uchun -5x va -9x ni birlashtirish.

$$-2-14x=-1$$

2 ni ikki tarafga qo’shing.

$$-14x=-1+2$$

1 olish uchun -1 va 2'ni qo'shing.

$$-14x=1$$

Ikki tarafini -14 ga bo‘ling.

$$x=\frac{1}{-14}$$

\frac{1}{-14} kasri manfiy belgini olib tashlash bilan -\frac{1}{14} sifatida qayta yozilishi mumkin.

$$x=-\frac{1}{14}$$
