Yechim qadamlari

-13\times \frac{2}{3} ni yagona kasrga aylantiring.

$$\frac{-13\times 2}{3}-0\times 34\times \frac{2}{7}+\frac{1}{3}\times 13-\frac{5}{7}\times 0\times 34$$

-26 hosil qilish uchun -13 va 2 ni ko'paytirish.

$$\frac{-26}{3}-0\times 34\times \frac{2}{7}+\frac{1}{3}\times 13-\frac{5}{7}\times 0\times 34$$

\frac{-26}{3} kasri manfiy belgini olib tashlash bilan -\frac{26}{3} sifatida qayta yozilishi mumkin.

$$-\frac{26}{3}-0\times 34\times \frac{2}{7}+\frac{1}{3}\times 13-\frac{5}{7}\times 0\times 34$$

0 hosil qilish uchun 0 va 34 ni ko'paytirish.

$$-\frac{26}{3}-0\times \frac{2}{7}+\frac{1}{3}\times 13-\frac{5}{7}\times 0\times 34$$

0 hosil qilish uchun 0 va \frac{2}{7} ni ko'paytirish.

$$-\frac{26}{3}-0+\frac{1}{3}\times 13-\frac{5}{7}\times 0\times 34$$

-\frac{26}{3} olish uchun -\frac{26}{3} dan 0 ni ayirish.

$$-\frac{26}{3}+\frac{1}{3}\times 13-\frac{5}{7}\times 0\times 34$$

\frac{13}{3} hosil qilish uchun \frac{1}{3} va 13 ni ko'paytirish.

$$-\frac{26}{3}+\frac{13}{3}-\frac{5}{7}\times 0\times 34$$

-\frac{26}{3} va \frac{13}{3} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-26+13}{3}-\frac{5}{7}\times 0\times 34$$

-13 olish uchun -26 va 13'ni qo'shing.

$$-\frac{13}{3}-\frac{5}{7}\times 0\times 34$$

0 hosil qilish uchun \frac{5}{7} va 0 ni ko'paytirish.

$$-\frac{13}{3}-0\times 34$$

0 hosil qilish uchun 0 va 34 ni ko'paytirish.

$$-\frac{13}{3}-0$$

-\frac{13}{3} olish uchun -\frac{13}{3} dan 0 ni ayirish.

$$-\frac{13}{3}$$

Omil

$$-\frac{13}{3} = -4\frac{1}{3} = -4,333333333333333$$
