12-2\left(2x-1\right)=6-3x
Tenglamaning ikkala tarafini 6 ga, 3,2 ning eng kichik karralisiga ko‘paytiring.
12-4x+2=6-3x
-2 ga 2x-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
14-4x=6-3x
14 olish uchun 12 va 2'ni qo'shing.
14-4x+3x=6
3x ni ikki tarafga qo’shing.
14-x=6
-x ni olish uchun -4x va 3x ni birlashtirish.
-x=6-14
Ikkala tarafdan 14 ni ayirish.
-x=-8
-8 olish uchun 6 dan 14 ni ayirish.
x=8
Ikkala tarafini -1 ga ko‘paytiring.
