Chiziqli tenglamalarni yechish bo'yicha qadamlar

16 hosil qilish uchun 4 va 4 ni ko'paytirish.

$$8x-16x-8\left(-4\right)x+4=4x-9$$

-8x ni olish uchun 8x va -16x ni birlashtirish.

$$-8x-8\left(-4\right)x+4=4x-9$$

-32 hosil qilish uchun 8 va -4 ni ko'paytirish.

$$-8x-\left(-32x\right)+4=4x-9$$

-32x ning teskarisi 32x ga teng.

$$-8x+32x+4=4x-9$$

24x ni olish uchun -8x va 32x ni birlashtirish.

$$24x+4=4x-9$$

Ikkala tarafdan 4x ni ayirish.

$$24x+4-4x=-9$$

20x ni olish uchun 24x va -4x ni birlashtirish.

$$20x+4=-9$$

Ikkala tarafdan 4 ni ayirish.

$$20x=-9-4$$

-13 olish uchun -9 dan 4 ni ayirish.

$$20x=-13$$

Ikki tarafini 20 ga bo‘ling.

$$x=\frac{-13}{20}$$

\frac{-13}{20} kasri manfiy belgini olib tashlash bilan -\frac{13}{20} sifatida qayta yozilishi mumkin.

$$x=-\frac{13}{20}$$
