3u+1+8u+2=3\left(u-3\right)
-2 ga -4u-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
11u+1+2=3\left(u-3\right)
11u ni olish uchun 3u va 8u ni birlashtirish.
11u+3=3\left(u-3\right)
3 olish uchun 1 va 2'ni qo'shing.
11u+3=3u-9
3 ga u-3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
11u+3-3u=-9

8u+3=-9
8u ni olish uchun 11u va -3u ni birlashtirish.
8u=-9-3
Ikkala tarafdan 3 ni ayirish.
8u=-12
-12 olish uchun -9 dan 3 ni ayirish.
u=\frac{-12}{8}
