4x-2\left(x-1\right)=8-\left(x+2\right)
Tenglamaning ikkala tarafini 4 ga, 2,4 ning eng kichik karralisiga ko‘paytiring.
4x-2x+2=8-\left(x+2\right)
-2 ga x-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
2x+2=8-\left(x+2\right)
2x ni olish uchun 4x va -2x ni birlashtirish.
2x+2=8-x-2
x+2 teskarisini topish uchun har birining teskarisini toping.
2x+2=6-x
6 olish uchun 8 dan 2 ni ayirish.
2x+2+x=6
x ni ikki tarafga qo’shing.
3x+2=6
3x ni olish uchun 2x va x ni birlashtirish.
3x=6-2
Ikkala tarafdan 2 ni ayirish.
3x=4
4 olish uchun 6 dan 2 ni ayirish.
x=\frac{4}{3}
Ikki tarafini 3 ga bo‘ling.
