Chiziqli tenglamalarni yechish bo'yicha qadamlar

\frac{8}{7} ni ikki tarafga qo’shing.

$$-\frac{1}{2}x=-\frac{4}{5}+\frac{8}{7}$$

5 va 7 ning eng kichik umumiy karralisi 35 ga teng. -\frac{4}{5} va \frac{8}{7} ni 35 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{1}{2}x=-\frac{28}{35}+\frac{40}{35}$$

-\frac{28}{35} va \frac{40}{35} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$-\frac{1}{2}x=\frac{-28+40}{35}$$

12 olish uchun -28 va 40'ni qo'shing.

$$-\frac{1}{2}x=\frac{12}{35}$$

Ikki tarafini -2 va teskari kasri -\frac{1}{2} ga ko‘paytiring.

$$x=\frac{12}{35}\left(-2\right)$$

\frac{12}{35}\left(-2\right) ni yagona kasrga aylantiring.

$$x=\frac{12\left(-2\right)}{35}$$

-24 hosil qilish uchun 12 va -2 ni ko'paytirish.

$$x=\frac{-24}{35}$$

\frac{-24}{35} kasri manfiy belgini olib tashlash bilan -\frac{24}{35} sifatida qayta yozilishi mumkin.

$$x=-\frac{24}{35}$$
