-\left(30+x\right)\times 120=\left(x-30\right)\times 60
x qiymati -30,30 qiymatlaridan birortasiga teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini \left(x-30\right)\left(x+30\right) ga, 30-x,30+x ning eng kichik karralisiga ko‘paytiring.
\left(-30-x\right)\times 120=\left(x-30\right)\times 60
30+x teskarisini topish uchun har birining teskarisini toping.
-3600-120x=\left(x-30\right)\times 60
-30-x ga 120 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-3600-120x=60x-1800
x-30 ga 60 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-3600-120x-60x=-1800
Ikkala tarafdan 60x ni ayirish.
-3600-180x=-1800
-180x ni olish uchun -120x va -60x ni birlashtirish.
-180x=-1800+3600
3600 ni ikki tarafga qo’shing.
-180x=1800
1800 olish uchun -1800 va 3600'ni qo'shing.
x=\frac{1800}{-180}
Ikki tarafini -180 ga bo‘ling.
x=-10
-10 ni olish uchun 1800 ni -180 ga bo‘ling.
