x\times 7-\left(x-1\right)\times 5=11
x qiymati 0,1 qiymatlaridan birortasiga teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini x\left(x-1\right) ga, x-1,x,x^{2}-x ning eng kichik karralisiga ko‘paytiring.
x\times 7-\left(5x-5\right)=11
x-1 ga 5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
x\times 7-5x+5=11
5x-5 teskarisini topish uchun har birining teskarisini toping.
2x+5=11
2x ni olish uchun x\times 7 va -5x ni birlashtirish.
2x=11-5
Ikkala tarafdan 5 ni ayirish.
2x=6
6 olish uchun 11 dan 5 ni ayirish.
x=\frac{6}{2}
Ikki tarafini 2 ga bo‘ling.
x=3
3 ni olish uchun 6 ni 2 ga bo‘ling.
