\left(y+2\right)\times 5-\left(2y-2\right)=\left(y-2\right)\times 6
y qiymati -2,2 qiymatlaridan birortasiga teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini \left(y-2\right)\left(y+2\right) ga, y-2,y^{2}-4,y+2 ning eng kichik karralisiga ko‘paytiring.
5y+10-\left(2y-2\right)=\left(y-2\right)\times 6
y+2 ga 5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
5y+10-2y+2=\left(y-2\right)\times 6
2y-2 teskarisini topish uchun har birining teskarisini toping.
3y+10+2=\left(y-2\right)\times 6
3y ni olish uchun 5y va -2y ni birlashtirish.
3y+12=\left(y-2\right)\times 6
12 olish uchun 10 va 2'ni qo'shing.
3y+12=6y-12
y-2 ga 6 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
3y+12-6y=-12
Ikkala tarafdan 6y ni ayirish.
-3y+12=-12
-3y ni olish uchun 3y va -6y ni birlashtirish.
-3y=-12-12
Ikkala tarafdan 12 ni ayirish.
-3y=-24
-24 olish uchun -12 dan 12 ni ayirish.
y=\frac{-24}{-3}
Ikki tarafini -3 ga bo‘ling.
y=8
8 ni olish uchun -24 ni -3 ga bo‘ling.
