Yechim qadamlari

30 hosil qilish uchun 5 va 6 ni ko'paytirish.

$$-\frac{30+5}{6}-\frac{9\times 3+2}{3}+\frac{17\times 4+3}{4}-\frac{3\times 2+1}{2}$$

35 olish uchun 30 va 5'ni qo'shing.

$$-\frac{35}{6}-\frac{9\times 3+2}{3}+\frac{17\times 4+3}{4}-\frac{3\times 2+1}{2}$$

27 hosil qilish uchun 9 va 3 ni ko'paytirish.

$$-\frac{35}{6}-\frac{27+2}{3}+\frac{17\times 4+3}{4}-\frac{3\times 2+1}{2}$$

29 olish uchun 27 va 2'ni qo'shing.

$$-\frac{35}{6}-\frac{29}{3}+\frac{17\times 4+3}{4}-\frac{3\times 2+1}{2}$$

6 va 3 ning eng kichik umumiy karralisi 6 ga teng. -\frac{35}{6} va \frac{29}{3} ni 6 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{35}{6}-\frac{58}{6}+\frac{17\times 4+3}{4}-\frac{3\times 2+1}{2}$$

-\frac{35}{6} va \frac{58}{6} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{-35-58}{6}+\frac{17\times 4+3}{4}-\frac{3\times 2+1}{2}$$

-93 olish uchun -35 dan 58 ni ayirish.

$$\frac{-93}{6}+\frac{17\times 4+3}{4}-\frac{3\times 2+1}{2}$$

\frac{-93}{6} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.

$$-\frac{31}{2}+\frac{17\times 4+3}{4}-\frac{3\times 2+1}{2}$$

68 hosil qilish uchun 17 va 4 ni ko'paytirish.

$$-\frac{31}{2}+\frac{68+3}{4}-\frac{3\times 2+1}{2}$$

71 olish uchun 68 va 3'ni qo'shing.

$$-\frac{31}{2}+\frac{71}{4}-\frac{3\times 2+1}{2}$$

2 va 4 ning eng kichik umumiy karralisi 4 ga teng. -\frac{31}{2} va \frac{71}{4} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$-\frac{62}{4}+\frac{71}{4}-\frac{3\times 2+1}{2}$$

-\frac{62}{4} va \frac{71}{4} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$\frac{-62+71}{4}-\frac{3\times 2+1}{2}$$

9 olish uchun -62 va 71'ni qo'shing.

$$\frac{9}{4}-\frac{3\times 2+1}{2}$$

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

$$\frac{9}{4}-\frac{6+1}{2}$$

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

$$\frac{9}{4}-\frac{7}{2}$$

4 va 2 ning eng kichik umumiy karralisi 4 ga teng. \frac{9}{4} va \frac{7}{2} ni 4 maxraj bilan kasrlarga aylantirib oling.

$$\frac{9}{4}-\frac{14}{4}$$

\frac{9}{4} va \frac{14}{4} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$\frac{9-14}{4}$$

-5 olish uchun 9 dan 14 ni ayirish.

$$-\frac{5}{4}$$
