2\left(x+1\right)-4=8-\left(3-x\right)
Tenglamaning ikkala tarafini 4 ga, 2,4 ning eng kichik karralisiga ko‘paytiring.
2x+2-4=8-\left(3-x\right)
2 ga x+1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
2x-2=8-\left(3-x\right)
-2 olish uchun 2 dan 4 ni ayirish.
2x-2=8-3-\left(-x\right)
3-x teskarisini topish uchun har birining teskarisini toping.
2x-2=8-3+x
-x ning teskarisi x ga teng.
2x-2=5+x
5 olish uchun 8 dan 3 ni ayirish.
2x-2-x=5
Ikkala tarafdan x ni ayirish.
x-2=5
x ni olish uchun 2x va -x ni birlashtirish.
x=5+2
2 ni ikki tarafga qo’shing.
x=7
7 olish uchun 5 va 2'ni qo'shing.
