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

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

x uchun yechish

$$x = -\frac{3}{2} = -1\frac{1}{2} = -1,5$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

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

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

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

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

-1 olish uchun 2 dan 3 ni ayirish.

$$-2x-1=2$$

1 ni ikki tarafga qo’shing.

$$-2x=2+1$$

3 olish uchun 2 va 1'ni qo'shing.

$$-2x=3$$

Ikki tarafini -2 ga bo‘ling.

$$x=\frac{3}{-2}$$

\frac{3}{-2} kasri manfiy belgini olib tashlash bilan -\frac{3}{2} sifatida qayta yozilishi mumkin.

$$x=-\frac{3}{2}$$
