Yechim qadamlari

20 hosil qilish uchun 5 va 4 ni ko'paytirish.

$$-\frac{20+3}{4}+\frac{2\times 7+3}{7}-\frac{1\times 4+1}{4}-\left(-\frac{4}{7}\right)$$

23 olish uchun 20 va 3'ni qo'shing.

$$-\frac{23}{4}+\frac{2\times 7+3}{7}-\frac{1\times 4+1}{4}-\left(-\frac{4}{7}\right)$$

14 hosil qilish uchun 2 va 7 ni ko'paytirish.

$$-\frac{23}{4}+\frac{14+3}{7}-\frac{1\times 4+1}{4}-\left(-\frac{4}{7}\right)$$

17 olish uchun 14 va 3'ni qo'shing.

$$-\frac{23}{4}+\frac{17}{7}-\frac{1\times 4+1}{4}-\left(-\frac{4}{7}\right)$$

4 va 7 ning eng kichik umumiy karralisi 28 ga teng. -\frac{23}{4} va \frac{17}{7} ni 28 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{161}{28}+\frac{68}{28}-\frac{1\times 4+1}{4}-\left(-\frac{4}{7}\right)$$

-\frac{161}{28} va \frac{68}{28} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-161+68}{28}-\frac{1\times 4+1}{4}-\left(-\frac{4}{7}\right)$$

-93 olish uchun -161 va 68'ni qo'shing.

$$-\frac{93}{28}-\frac{1\times 4+1}{4}-\left(-\frac{4}{7}\right)$$

4 hosil qilish uchun 1 va 4 ni ko'paytirish.

$$-\frac{93}{28}-\frac{4+1}{4}-\left(-\frac{4}{7}\right)$$

5 olish uchun 4 va 1'ni qo'shing.

$$-\frac{93}{28}-\frac{5}{4}-\left(-\frac{4}{7}\right)$$

28 va 4 ning eng kichik umumiy karralisi 28 ga teng. -\frac{93}{28} va \frac{5}{4} ni 28 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{93}{28}-\frac{35}{28}-\left(-\frac{4}{7}\right)$$

-\frac{93}{28} va \frac{35}{28} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-93-35}{28}-\left(-\frac{4}{7}\right)$$

-128 olish uchun -93 dan 35 ni ayirish.

$$\frac{-128}{28}-\left(-\frac{4}{7}\right)$$

\frac{-128}{28} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{32}{7}-\left(-\frac{4}{7}\right)$$

-\frac{4}{7} ning teskarisi \frac{4}{7} ga teng.

$$-\frac{32}{7}+\frac{4}{7}$$

-\frac{32}{7} va \frac{4}{7} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-32+4}{7}$$

-28 olish uchun -32 va 4'ni qo'shing.

$$\frac{-28}{7}$$

-4 ni olish uchun -28 ni 7 ga bo‘ling.
