15+5x=-2x-14
-2 ga x+7 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
15+5x+2x=-14
2x ni ikki tarafga qo’shing.
15+7x=-14
7x ni olish uchun 5x va 2x ni birlashtirish.
7x=-14-15
Ikkala tarafdan 15 ni ayirish.
7x=-29
-29 olish uchun -14 dan 15 ni ayirish.
x=\frac{-29}{7}
Ikki tarafini 7 ga bo‘ling.
x=-\frac{29}{7}
\frac{-29}{7} kasri manfiy belgini olib tashlash bilan -\frac{29}{7} sifatida qayta yozilishi mumkin.
