6u-2\left(u-1\right)=6u-3\left(1-u\right)
Tenglamaning ikkala tarafini 6 ga, 3,2 ning eng kichik karralisiga ko‘paytiring.
6u-2u+2=6u-3\left(1-u\right)
-2 ga u-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
4u+2=6u-3\left(1-u\right)
4u ni olish uchun 6u va -2u ni birlashtirish.
4u+2=6u-3+3u
-3 ga 1-u ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
4u+2=9u-3
