12\left(x-1\right)=19\left(x-12\right)
x qiymati 1 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 38\left(x-1\right) ga, 19,2x-2 ning eng kichik karralisiga ko‘paytiring.
12x-12=19\left(x-12\right)
12 ga x-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
12x-12=19x-228
19 ga x-12 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
12x-12-19x=-228
Ikkala tarafdan 19x ni ayirish.
-7x-12=-228
-7x ni olish uchun 12x va -19x ni birlashtirish.
-7x=-228+12
12 ni ikki tarafga qo’shing.
-7x=-216
-216 olish uchun -228 va 12'ni qo'shing.
x=\frac{-216}{-7}
Ikki tarafini -7 ga bo‘ling.
x=\frac{216}{7}
Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-216}{-7} kasrini \frac{216}{7} ga soddalashtirish mumkin.
