3\left(3-3y\right)=1-6y
Tenglamaning ikkala tarafini 6 ga, 2,6 ning eng kichik karralisiga ko‘paytiring.
9-9y=1-6y
3 ga 3-3y ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
9-9y+6y=1
6y ni ikki tarafga qo’shing.
9-3y=1
-3y ni olish uchun -9y va 6y ni birlashtirish.
-3y=1-9
Ikkala tarafdan 9 ni ayirish.
-3y=-8
-8 olish uchun 1 dan 9 ni ayirish.
y=\frac{-8}{-3}
Ikki tarafini -3 ga bo‘ling.
y=\frac{8}{3}
Ikkala surat va maxrajdan manfiy belgini olib tashlash bilan \frac{-8}{-3} kasrini \frac{8}{3} ga soddalashtirish mumkin.
