\left(x+1\right)\times 4+\left(x-1\right)\times 2=35
x qiymati -1,1 qiymatlaridan birortasiga teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini \left(x-1\right)\left(x+1\right) ga, x-1,x+1,x^{2}-1 ning eng kichik karralisiga ko‘paytiring.
4x+4+\left(x-1\right)\times 2=35
x+1 ga 4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
4x+4+2x-2=35
x-1 ga 2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
6x+4-2=35
6x ni olish uchun 4x va 2x ni birlashtirish.
6x+2=35
2 olish uchun 4 dan 2 ni ayirish.
6x=35-2
Ikkala tarafdan 2 ni ayirish.
6x=33
33 olish uchun 35 dan 2 ni ayirish.
x=\frac{33}{6}
Ikki tarafini 6 ga bo‘ling.
x=\frac{11}{2}
\frac{33}{6} ulushini 3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
