k uchun yechish
k=\frac{n-2}{2}
n uchun yechish
n=2\left(k+1\right)
Baham ko'rish
Klipbordga nusxa olish
-2k=2-n
Ikkala tarafdan n ni ayirish.
\frac{-2k}{-2}=\frac{2-n}{-2}
Ikki tarafini -2 ga bo‘ling.
k=\frac{2-n}{-2}
-2 ga bo'lish -2 ga ko'paytirishni bekor qiladi.
k=\frac{n}{2}-1
2-n ni -2 ga bo'lish.
n=2+2k
2k ni ikki tarafga qo’shing.
