-7(4+4p)+3p=8p-4(p+7 eching

$$- 7 ( 4 + 4 p ) + 3 p = 8 p - 4 ( p + 7$$

p uchun yechish

$$p=0$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

-7 ga 4+4p ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$-28-28p+3p=8p-4\left(p+7\right)$$

-25p ni olish uchun -28p va 3p ni birlashtirish.

$$-28-25p=8p-4\left(p+7\right)$$

-4 ga p+7 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$-28-25p=8p-4p-28$$

4p ni olish uchun 8p va -4p ni birlashtirish.

$$-28-25p=4p-28$$

Ikkala tarafdan 4p ni ayirish.

$$-28-25p-4p=-28$$

-29p ni olish uchun -25p va -4p ni birlashtirish.

$$-28-29p=-28$$

28 ni ikki tarafga qo’shing.

$$-29p=-28+28$$

0 olish uchun -28 va 28'ni qo'shing.

$$-29p=0$$

Ikki son koʻpaytmasi 0 ga teng, agar kamida bittasi 0 bo‘lsa. -29 0 ga teng bo‘lmasa, p 0 ga teng bo‘lishi kerak.

$$p=0$$
