Chiziqli tenglamalarni yechish bo'yicha qadamlar

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

$$4+2x-6-7x=13x-1+4x$$

-2 olish uchun 4 dan 6 ni ayirish.

$$-2+2x-7x=13x-1+4x$$

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

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

17x ni olish uchun 13x va 4x ni birlashtirish.

$$-2-5x=17x-1$$

Ikkala tarafdan 17x ni ayirish.

$$-2-5x-17x=-1$$

-22x ni olish uchun -5x va -17x ni birlashtirish.

$$-2-22x=-1$$

2 ni ikki tarafga qo’shing.

$$-22x=-1+2$$

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

$$-22x=1$$

Ikki tarafini -22 ga bo‘ling.

$$x=\frac{1}{-22}$$

\frac{1}{-22} kasri manfiy belgini olib tashlash bilan -\frac{1}{22} sifatida qayta yozilishi mumkin.

$$x=-\frac{1}{22}$$
