7\pi x-15-2x=12
Ikkala tarafdan 2x ni ayirish.
7\pi x-2x=12+15
15 ni ikki tarafga qo’shing.
7\pi x-2x=27
27 olish uchun 12 va 15'ni qo'shing.
\left(7\pi -2\right)x=27
x'ga ega bo'lgan barcha shartlarni birlashtirish.
\frac{\left(7\pi -2\right)x}{7\pi -2}=\frac{27}{7\pi -2}
Ikki tarafini 7\pi -2 ga bo‘ling.
x=\frac{27}{7\pi -2}
7\pi -2 ga bo'lish 7\pi -2 ga ko'paytirishni bekor qiladi.
