Baham ko'rish
Klipbordga nusxa olish
5\times 2c-3\times 4c=105
Tenglamaning ikkala tarafini 15 ga, 3,5 ning eng kichik karralisiga ko‘paytiring.
10c-3\times 4c=105
10 hosil qilish uchun 5 va 2 ni ko'paytirish.
10c-12c=105
-12 hosil qilish uchun -3 va 4 ni ko'paytirish.
-2c=105
-2c ni olish uchun 10c va -12c ni birlashtirish.
c=\frac{105}{-2}
Ikki tarafini -2 ga bo‘ling.
c=-\frac{105}{2}
\frac{105}{-2} kasri manfiy belgini olib tashlash bilan -\frac{105}{2} sifatida qayta yozilishi mumkin.
