5x-4+3=2left(x-4right)+x eching

$$5x-4+3 = 2 \left( x-4 \right) +x$$

x uchun yechish

$$x = -\frac{7}{2} = -3\frac{1}{2} = -3,5$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

-1 olish uchun -4 va 3'ni qo'shing.

$$5x-1=2\left(x-4\right)+x$$

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

$$5x-1=2x-8+x$$

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

$$5x-1=3x-8$$

Ikkala tarafdan 3x ni ayirish.

$$5x-1-3x=-8$$

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

$$2x-1=-8$$

1 ni ikki tarafga qo’shing.

$$2x=-8+1$$

-7 olish uchun -8 va 1'ni qo'shing.

$$2x=-7$$

Ikki tarafini 2 ga bo‘ling.

$$x=\frac{-7}{2}$$

\frac{-7}{2} kasri manfiy belgini olib tashlash bilan -\frac{7}{2} sifatida qayta yozilishi mumkin.

$$x=-\frac{7}{2}$$
