fn=-n
Ikkala tarafdan n ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.
nf=-n
Tenglama standart shaklda.
\frac{nf}{n}=-\frac{n}{n}
Ikki tarafini n ga bo‘ling.
f=-\frac{n}{n}
n ga bo'lish n ga ko'paytirishni bekor qiladi.
f=-1
-n ni n ga bo'lish.
\left(f+1\right)n=0
n'ga ega bo'lgan barcha shartlarni birlashtirish.
n=0
0 ni f+1 ga bo'lish.
