6-2x=5x
2 ga 3-x ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
6-2x-5x=0
Ikkala tarafdan 5x ni ayirish.
6-7x=0
-7x ni olish uchun -2x va -5x ni birlashtirish.
-7x=-6
Ikkala tarafdan 6 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.
x=\frac{-6}{-7}
Ikki tarafini -7 ga bo‘ling.
x=\frac{6}{7}
Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-6}{-7} kasrini \frac{6}{7} ga soddalashtirish mumkin.
