5(z+8)-7=(z+8)+13 eching

$$5 ( z + 8 ) - 7 = ( z + 8 ) + 13$$

z uchun yechish

$$z=-3$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

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

$$5z+40-7=z+8+13$$

33 olish uchun 40 dan 7 ni ayirish.

$$5z+33=z+8+13$$

21 olish uchun 8 va 13'ni qo'shing.

$$5z+33=z+21$$

Ikkala tarafdan z ni ayirish.

$$5z+33-z=21$$

4z ni olish uchun 5z va -z ni birlashtirish.

$$4z+33=21$$

Ikkala tarafdan 33 ni ayirish.

$$4z=21-33$$

-12 olish uchun 21 dan 33 ni ayirish.

$$4z=-12$$

Ikki tarafini 4 ga bo‘ling.

$$z=\frac{-12}{4}$$

-3 ni olish uchun -12 ni 4 ga bo‘ling.

$$z=-3$$
