3left(3-xright)+9=2(x-4)+6 eching

$$3 \left( 3-x \right) +9=2(x-4)+6$$

x uchun yechish

$$x=4$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

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

$$9-3x+9=2\left(x-4\right)+6$$

18 olish uchun 9 va 9'ni qo'shing.

$$18-3x=2\left(x-4\right)+6$$

2 ga x-4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$18-3x=2x-8+6$$

-2 olish uchun -8 va 6'ni qo'shing.

$$18-3x=2x-2$$

Ikkala tarafdan 2x ni ayirish.

$$18-3x-2x=-2$$

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

$$18-5x=-2$$

Ikkala tarafdan 18 ni ayirish.

$$-5x=-2-18$$

-20 olish uchun -2 dan 18 ni ayirish.

$$-5x=-20$$

Ikki tarafini -5 ga bo‘ling.

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

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

$$x=4$$
