Baham ko'rish
Klipbordga nusxa olish
n+y+n=91
n ni ikki tarafga qo’shing.
2n+y=91
2n ni olish uchun n va n ni birlashtirish.
2n=91-y
Ikkala tarafdan y ni ayirish.
\frac{2n}{2}=\frac{91-y}{2}
Ikki tarafini 2 ga bo‘ling.
n=\frac{91-y}{2}
2 ga bo'lish 2 ga ko'paytirishni bekor qiladi.
y=91-n-n
Ikkala tarafdan n ni ayirish.
y=91-2n
-2n ni olish uchun -n va -n ni birlashtirish.
