7\left(2p+1\right)=5p+6
p qiymati -\frac{6}{5} teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 7\left(5p+6\right) ga, 5p+6,7 ning eng kichik karralisiga ko‘paytiring.
14p+7=5p+6
7 ga 2p+1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
14p+7-5p=6
Ikkala tarafdan 5p ni ayirish.
9p+7=6
9p ni olish uchun 14p va -5p ni birlashtirish.
9p=6-7
Ikkala tarafdan 7 ni ayirish.
9p=-1
-1 olish uchun 6 dan 7 ni ayirish.
p=\frac{-1}{9}
Ikki tarafini 9 ga bo‘ling.
p=-\frac{1}{9}
\frac{-1}{9} kasri manfiy belgini olib tashlash bilan -\frac{1}{9} sifatida qayta yozilishi mumkin.
