6+6\left(x+3\right)\times \frac{1}{2}=2\left(x+3\right)
x qiymati -3 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 6\left(x+3\right) ga, x+3,2,3 ning eng kichik karralisiga ko‘paytiring.
6+3\left(x+3\right)=2\left(x+3\right)
3 hosil qilish uchun 6 va \frac{1}{2} ni ko'paytirish.
6+3x+9=2\left(x+3\right)
3 ga x+3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
15+3x=2\left(x+3\right)
15 olish uchun 6 va 9'ni qo'shing.
15+3x=2x+6
2 ga x+3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
15+3x-2x=6
Ikkala tarafdan 2x ni ayirish.
15+x=6
x ni olish uchun 3x va -2x ni birlashtirish.
x=6-15
Ikkala tarafdan 15 ni ayirish.
x=-9
-9 olish uchun 6 dan 15 ni ayirish.
