Baham ko'rish
Klipbordga nusxa olish
\left(a+3\right)\times 2500=a\times 2000\times 2
a qiymati -3,0 qiymatlaridan birortasiga teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini a\left(a+3\right) ga, a,a+3 ning eng kichik karralisiga ko‘paytiring.
2500a+7500=a\times 2000\times 2
a+3 ga 2500 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
2500a+7500=a\times 4000
4000 hosil qilish uchun 2000 va 2 ni ko'paytirish.
2500a+7500-a\times 4000=0
Ikkala tarafdan a\times 4000 ni ayirish.
-1500a+7500=0
-1500a ni olish uchun 2500a va -a\times 4000 ni birlashtirish.
-1500a=-7500
Ikkala tarafdan 7500 ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.
a=\frac{-7500}{-1500}
Ikki tarafini -1500 ga bo‘ling.
a=5
5 ni olish uchun -7500 ni -1500 ga bo‘ling.
