3(x+1)=5(x-2)+7 eching

$$3 ( x + 1 ) = 5 ( x - 2 ) + 7$$

x uchun yechish

$$x=3$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

3 ga x+1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$3x+3=5\left(x-2\right)+7$$

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

$$3x+3=5x-10+7$$

-3 olish uchun -10 va 7'ni qo'shing.

$$3x+3=5x-3$$

Ikkala tarafdan 5x ni ayirish.

$$3x+3-5x=-3$$

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

$$-2x+3=-3$$

Ikkala tarafdan 3 ni ayirish.

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

-6 olish uchun -3 dan 3 ni ayirish.

$$-2x=-6$$

Ikki tarafini -2 ga bo‘ling.

$$x=\frac{-6}{-2}$$

3 ni olish uchun -6 ni -2 ga bo‘ling.

$$x=3$$
