8\left(x-14\right)=7\left(x-12\right)
x qiymati 12 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 8\left(x-12\right) ga, x-12,8 ning eng kichik karralisiga ko‘paytiring.
8x-112=7\left(x-12\right)
8 ga x-14 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
8x-112=7x-84
7 ga x-12 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
8x-112-7x=-84
Ikkala tarafdan 7x ni ayirish.
x-112=-84
x ni olish uchun 8x va -7x ni birlashtirish.
x=-84+112
112 ni ikki tarafga qo’shing.
x=28
28 olish uchun -84 va 112'ni qo'shing.
