-9(z+8)=-9z-72 eching

$$- 9 ( z + 8 ) = - 9 z - 72$$

z uchun yechish (complex solution)

$$z\in \mathrm{C}$$

Yechim qadamlari

-9 ga z+8 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$-9z-72=-9z-72$$

9z ni ikki tarafga qo’shing.

$$-9z-72+9z=-72$$

0 ni olish uchun -9z va 9z ni birlashtirish.

$$-72=-72$$

-72 va -72 ni taqqoslang.

$$\text{true}$$

Bu har qanday z uchun to‘g‘ri.
