2\left(4x+7\right)=3\left(2x+9\right)
x qiymati -\frac{9}{2} teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 2\left(2x+9\right) ga, 2x+9,2 ning eng kichik karralisiga ko‘paytiring.
8x+14=3\left(2x+9\right)
2 ga 4x+7 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
8x+14=6x+27
3 ga 2x+9 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
8x+14-6x=27
Ikkala tarafdan 6x ni ayirish.
2x+14=27
2x ni olish uchun 8x va -6x ni birlashtirish.
2x=27-14
Ikkala tarafdan 14 ni ayirish.
2x=13
13 olish uchun 27 dan 14 ni ayirish.
x=\frac{13}{2}
Ikki tarafini 2 ga bo‘ling.
