7\times 3+7\left(x+1\right)\times \frac{2}{7}=14\left(x+1\right)
x qiymati -1 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 7\left(x+1\right) ga, x+1,7 ning eng kichik karralisiga ko‘paytiring.
21+7\left(x+1\right)\times \frac{2}{7}=14\left(x+1\right)
21 hosil qilish uchun 7 va 3 ni ko'paytirish.
21+2\left(x+1\right)=14\left(x+1\right)
2 hosil qilish uchun 7 va \frac{2}{7} ni ko'paytirish.
21+2x+2=14\left(x+1\right)
2 ga x+1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
23+2x=14\left(x+1\right)
23 olish uchun 21 va 2'ni qo'shing.
23+2x=14x+14
14 ga x+1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
23+2x-14x=14
Ikkala tarafdan 14x ni ayirish.
23-12x=14
-12x ni olish uchun 2x va -14x ni birlashtirish.
-12x=14-23
Ikkala tarafdan 23 ni ayirish.
-12x=-9
-9 olish uchun 14 dan 23 ni ayirish.
x=\frac{-9}{-12}
Ikki tarafini -12 ga bo‘ling.
x=\frac{3}{4}
\frac{-9}{-12} ulushini -3 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
