5*4(x+3)=-4(x+3)*-3 eching

$$5 \cdot 4 ( x + 3 ) = - 4 ( x + 3 ) \cdot - 3$$

x uchun yechish

$$x=-3$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

20 hosil qilish uchun 5 va 4 ni ko'paytirish.

$$20\left(x+3\right)=-4\left(x+3\right)\left(-3\right)$$

20 ga x+3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$20x+60=-4\left(x+3\right)\left(-3\right)$$

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

$$20x+60=12\left(x+3\right)$$

12 ga x+3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$20x+60=12x+36$$

Ikkala tarafdan 12x ni ayirish.

$$20x+60-12x=36$$

8x ni olish uchun 20x va -12x ni birlashtirish.

$$8x+60=36$$

Ikkala tarafdan 60 ni ayirish.

$$8x=36-60$$

-24 olish uchun 36 dan 60 ni ayirish.

$$8x=-24$$

Ikki tarafini 8 ga bo‘ling.

$$x=\frac{-24}{8}$$

-3 ni olish uchun -24 ni 8 ga bo‘ling.

$$x=-3$$
