Baham ko'rish
Klipbordga nusxa olish
10n\times 10\times \frac{-4}{100}=300
n qiymati 0 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 300n ga, 30,100,n ning eng kichik karralisiga ko‘paytiring.
100n\times \frac{-4}{100}=300
100 hosil qilish uchun 10 va 10 ni ko'paytirish.
100n\left(-\frac{1}{25}\right)=300
\frac{-4}{100} ulushini 4 ni chiqarib, bekor qilish hisobiga eng past shartlarga kamaytiring.
\frac{100\left(-1\right)}{25}n=300
100\left(-\frac{1}{25}\right) ni yagona kasrga aylantiring.
\frac{-100}{25}n=300
-100 hosil qilish uchun 100 va -1 ni ko'paytirish.
-4n=300
-4 ni olish uchun -100 ni 25 ga bo‘ling.
n=\frac{300}{-4}
Ikki tarafini -4 ga bo‘ling.
n=-75
-75 ni olish uchun 300 ni -4 ga bo‘ling.
