Chiziqli tenglamalarni yechish bo'yicha qadamlar

\frac{2}{3} ni ikki tarafga qo’shing.

$$-\frac{1}{5}x=-\frac{3}{4}+\frac{2}{3}$$

4 va 3 ning eng kichik umumiy karralisi 12 ga teng. -\frac{3}{4} va \frac{2}{3} ni 12 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{1}{5}x=-\frac{9}{12}+\frac{8}{12}$$

-\frac{9}{12} va \frac{8}{12} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$-\frac{1}{5}x=\frac{-9+8}{12}$$

-1 olish uchun -9 va 8'ni qo'shing.

$$-\frac{1}{5}x=-\frac{1}{12}$$

Ikki tarafini -5 va teskari kasri -\frac{1}{5} ga ko‘paytiring.

$$x=-\frac{1}{12}\left(-5\right)$$

-\frac{1}{12}\left(-5\right) ni yagona kasrga aylantiring.

$$x=\frac{-\left(-5\right)}{12}$$

5 hosil qilish uchun -1 va -5 ni ko'paytirish.

$$x=\frac{5}{12}$$
