35x+2=5\left(11x+7\right)
x qiymati -\frac{7}{11} teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 11x+7 ga ko'paytirish.
35x+2=55x+35
5 ga 11x+7 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
35x+2-55x=35
Ikkala tarafdan 55x ni ayirish.
-20x+2=35
-20x ni olish uchun 35x va -55x ni birlashtirish.
-20x=35-2
Ikkala tarafdan 2 ni ayirish.
-20x=33
33 olish uchun 35 dan 2 ni ayirish.
x=\frac{33}{-20}
Ikki tarafini -20 ga bo‘ling.
x=-\frac{33}{20}
\frac{33}{-20} kasri manfiy belgini olib tashlash bilan -\frac{33}{20} sifatida qayta yozilishi mumkin.
