\left(x+1\right)\times 2+x\times 3=\left(x+1\right)\times 4
x qiymati -1,0 qiymatlaridan birortasiga teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini x\left(x+1\right) ga, x,x+1 ning eng kichik karralisiga ko‘paytiring.
2x+2+x\times 3=\left(x+1\right)\times 4
x+1 ga 2 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
5x+2=\left(x+1\right)\times 4
5x ni olish uchun 2x va x\times 3 ni birlashtirish.
5x+2=4x+4
x+1 ga 4 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
5x+2-4x=4
Ikkala tarafdan 4x ni ayirish.
x+2=4
x ni olish uchun 5x va -4x ni birlashtirish.
x=4-2
Ikkala tarafdan 2 ni ayirish.
x=2
2 olish uchun 4 dan 2 ni ayirish.
