8(x-9)-9(x-8)=x+8-(x-4) eching

$$8(x-9)-9(x-8)=x+8-(x-4)$$

x uchun yechish

$$x=-12$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

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

$$8x-72-9\left(x-8\right)=x+8-\left(x-4\right)$$

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

$$8x-72-9x+72=x+8-\left(x-4\right)$$

-x ni olish uchun 8x va -9x ni birlashtirish.

$$-x-72+72=x+8-\left(x-4\right)$$

0 olish uchun -72 va 72'ni qo'shing.

$$-x=x+8-\left(x-4\right)$$

x-4 teskarisini topish uchun har birining teskarisini toping.

$$-x=x+8-x-\left(-4\right)$$

-4 ning teskarisi 4 ga teng.

$$-x=x+8-x+4$$

0 ni olish uchun x va -x ni birlashtirish.

$$-x=8+4$$

12 olish uchun 8 va 4'ni qo'shing.

$$-x=12$$

Ikkala tarafini -1 ga ko‘paytiring.

$$x=-12$$
