7-4(-9/2+3)=-2left(-9/2-2right) eching

$$7-4(- \frac{ 9 }{ 2 } +3) = -2 \left( - \frac{ 9 }{ 2 } -2 \right)$$

Tasdiqlamoq

Yechim qadamlari

3 ni \frac{6}{2} kasrga o‘giring.

$$7-4\left(-\frac{9}{2}+\frac{6}{2}\right)=-2\left(-\frac{9}{2}-2\right)$$

-\frac{9}{2} va \frac{6}{2} da bir xil maxraji bor, ularning suratini qo‘shish orqali qo‘shing.

$$7-4\times \frac{-9+6}{2}=-2\left(-\frac{9}{2}-2\right)$$

-3 olish uchun -9 va 6'ni qo'shing.

$$7-4\left(-\frac{3}{2}\right)=-2\left(-\frac{9}{2}-2\right)$$

4\left(-\frac{3}{2}\right) ni yagona kasrga aylantiring.

$$7-\frac{4\left(-3\right)}{2}=-2\left(-\frac{9}{2}-2\right)$$

-12 hosil qilish uchun 4 va -3 ni ko'paytirish.

$$7-\frac{-12}{2}=-2\left(-\frac{9}{2}-2\right)$$

-6 ni olish uchun -12 ni 2 ga bo‘ling.

$$7-\left(-6\right)=-2\left(-\frac{9}{2}-2\right)$$

-6 ning teskarisi 6 ga teng.

$$7+6=-2\left(-\frac{9}{2}-2\right)$$

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

$$13=-2\left(-\frac{9}{2}-2\right)$$

2 ni \frac{4}{2} kasrga o‘giring.

$$13=-2\left(-\frac{9}{2}-\frac{4}{2}\right)$$

-\frac{9}{2} va \frac{4}{2} da bir xil maxraji bor, ularning suratini ayirish orqali ayiring.

$$13=-2\times \frac{-9-4}{2}$$

-13 olish uchun -9 dan 4 ni ayirish.

$$13=-2\left(-\frac{13}{2}\right)$$

-2 ni -\frac{13}{2} marotabaga ko'paytirish.

$$13=13$$

13 va 13 ni taqqoslang.
