11\left(x+3\right)=9\left(x+7\right)
x qiymati -7 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 11\left(x+7\right) ga, x+7,11 ning eng kichik karralisiga ko‘paytiring.
11x+33=9\left(x+7\right)
11 ga x+3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
11x+33=9x+63
9 ga x+7 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
11x+33-9x=63
Ikkala tarafdan 9x ni ayirish.
2x+33=63
2x ni olish uchun 11x va -9x ni birlashtirish.
2x=63-33
Ikkala tarafdan 33 ni ayirish.
2x=30
30 olish uchun 63 dan 33 ni ayirish.
x=\frac{30}{2}
Ikki tarafini 2 ga bo‘ling.
x=15
15 ni olish uchun 30 ni 2 ga bo‘ling.
