\left(x+4\right)\times 4-\left(x+1\right)\times 5=0
x qiymati -4,-1 qiymatlaridan birortasiga teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini \left(x+1\right)\left(x+4\right) ga, x+1,x+4 ning eng kichik karralisiga ko‘paytiring.
4x+16-\left(x+1\right)\times 5=0
x+4 ga 4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
4x+16-\left(5x+5\right)=0
x+1 ga 5 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
4x+16-5x-5=0
5x+5 teskarisini topish uchun har birining teskarisini toping.
-x+16-5=0
-x ni olish uchun 4x va -5x ni birlashtirish.
-x+11=0
11 olish uchun 16 dan 5 ni ayirish.
-x=-11
Ikkala tarafdan 11 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.
x=11
Ikkala tarafini -1 ga ko‘paytiring.
