Chiziqli tenglamalarni yechish bo'yicha qadamlar

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

$$2x+6+3\left(x-7\right)=-35$$

3 ga x-7 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$2x+6+3x-21=-35$$

5x ni olish uchun 2x va 3x ni birlashtirish.

$$5x+6-21=-35$$

-15 olish uchun 6 dan 21 ni ayirish.

$$5x-15=-35$$

15 ni ikki tarafga qo’shing.

$$5x=-35+15$$

-20 olish uchun -35 va 15'ni qo'shing.

$$5x=-20$$

Ikki tarafini 5 ga bo‘ling.

$$x=\frac{-20}{5}$$

-4 ni olish uchun -20 ni 5 ga bo‘ling.

$$x=-4$$
