1+\left(x-1\right)\left(-2\right)=0
x qiymati 1 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini x-1 ga ko'paytirish.
1-2x+2=0
x-1 ga -2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
3-2x=0
3 olish uchun 1 va 2'ni qo'shing.
-2x=-3
Ikkala tarafdan 3 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.
x=\frac{-3}{-2}
Ikki tarafini -2 ga bo‘ling.
x=\frac{3}{2}
Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-3}{-2} kasrini \frac{3}{2} ga soddalashtirish mumkin.
