Baham ko'rish
Klipbordga nusxa olish
w-8=10w
Tenglamaning ikkala tarafini -2 ga ko'paytirish.
w-8-10w=0
Ikkala tarafdan 10w ni ayirish.
-9w-8=0
-9w ni olish uchun w va -10w ni birlashtirish.
-9w=8
8 ni ikki tarafga qo’shing. Har qanday songa nolni qo‘shsangiz, o‘zi chiqadi.
w=\frac{8}{-9}
Ikki tarafini -9 ga bo‘ling.
w=-\frac{8}{9}
\frac{8}{-9} kasri manfiy belgini olib tashlash bilan -\frac{8}{9} sifatida qayta yozilishi mumkin.
