Yechim qadamlari

6 hosil qilish uchun 3 va 2 ni ko'paytirish.

$$-\frac{6+1}{2}-\frac{2\times 3+1}{3}$$

7 olish uchun 6 va 1'ni qo'shing.

$$-\frac{7}{2}-\frac{2\times 3+1}{3}$$

6 hosil qilish uchun 2 va 3 ni ko'paytirish.

$$-\frac{7}{2}-\frac{6+1}{3}$$

7 olish uchun 6 va 1'ni qo'shing.

$$-\frac{7}{2}-\frac{7}{3}$$

2 va 3 ning eng kichik umumiy karralisi 6 ga teng. -\frac{7}{2} va \frac{7}{3} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{21}{6}-\frac{14}{6}$$

-\frac{21}{6} va \frac{14}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-21-14}{6}$$

-35 olish uchun -21 dan 14 ni ayirish.

$$-\frac{35}{6}$$

Omil

$$-\frac{35}{6} = -5\frac{5}{6} = -5,833333333333333$$
