7\left(3X-2\right)=4\left(2X-3\right)
X qiymati \frac{3}{2} teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 7\left(2X-3\right) ga, 2X-3,7 ning eng kichik karralisiga ko‘paytiring.
21X-14=4\left(2X-3\right)
7 ga 3X-2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
21X-14=8X-12
4 ga 2X-3 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
21X-14-8X=-12
Ikkala tarafdan 8X ni ayirish.
13X-14=-12
13X ni olish uchun 21X va -8X ni birlashtirish.
13X=-12+14
14 ni ikki tarafga qo’shing.
13X=2
2 olish uchun -12 va 14'ni qo'shing.
X=\frac{2}{13}
Ikki tarafini 13 ga bo‘ling.
