nx+5-n=-2x
Ikkala tarafdan n ni ayirish.
nx-n=-2x-5
Ikkala tarafdan 5 ni ayirish.
\left(x-1\right)n=-2x-5
n'ga ega bo'lgan barcha shartlarni birlashtirish.
\frac{\left(x-1\right)n}{x-1}=\frac{-2x-5}{x-1}
Ikki tarafini x-1 ga bo‘ling.
n=\frac{-2x-5}{x-1}
x-1 ga bo'lish x-1 ga ko'paytirishni bekor qiladi.
n=-\frac{2x+5}{x-1}
-2x-5 ni x-1 ga bo'lish.
nx+5+2x=n
2x ni ikki tarafga qo’shing.
nx+2x=n-5
Ikkala tarafdan 5 ni ayirish.
\left(n+2\right)x=n-5
x'ga ega bo'lgan barcha shartlarni birlashtirish.
\frac{\left(n+2\right)x}{n+2}=\frac{n-5}{n+2}
Ikki tarafini n+2 ga bo‘ling.
x=\frac{n-5}{n+2}
n+2 ga bo'lish n+2 ga ko'paytirishni bekor qiladi.
