xy+y=0
Tenglamaning ikkala tarafini x ga ko'paytirish.
\left(x+1\right)y=0
y'ga ega bo'lgan barcha shartlarni birlashtirish.
y=0
0 ni x+1 ga bo'lish.
xy+y=0
x qiymati 0 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini x ga ko'paytirish.
xy=-y
Ikkala tarafdan y ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.
yx=-y
Tenglama standart shaklda.
\frac{yx}{y}=-\frac{y}{y}
Ikki tarafini y ga bo‘ling.
x=-\frac{y}{y}
y ga bo'lish y ga ko'paytirishni bekor qiladi.
x=-1
-y ni y ga bo'lish.
xy+y=0
Tenglamaning ikkala tarafini x ga ko'paytirish.
\left(x+1\right)y=0
y'ga ega bo'lgan barcha shartlarni birlashtirish.
y=0
0 ni x+1 ga bo'lish.
