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

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

x uchun yechish

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

Chiziqli tenglamalarni yechish bo'yicha qadamlar

2 ga 2x-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.

$$4x-2-1=3\times 2x+2$$

-3 olish uchun -2 dan 1 ni ayirish.

$$4x-3=3\times 2x+2$$

6 hosil qilish uchun 3 va 2 ni ko'paytirish.

$$4x-3=6x+2$$

Ikkala tarafdan 6x ni ayirish.

$$4x-3-6x=2$$

-2x ni olish uchun 4x va -6x ni birlashtirish.

$$-2x-3=2$$

3 ni ikki tarafga qo’shing.

$$-2x=2+3$$

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

$$-2x=5$$

Ikki tarafini -2 ga bo‘ling.

$$x=\frac{5}{-2}$$

\frac{5}{-2} kasri manfiy belgini olib tashlash bilan -\frac{5}{2} sifatida qayta yozilishi mumkin.

$$x=-\frac{5}{2}$$
