-96=\pi \left(2\times 9\left(n-1\right)-2\right)
Tenglamaning ikkala tarafini 2 ga ko'paytirish.
-96=\pi \left(18\left(n-1\right)-2\right)
18 hosil qilish uchun 2 va 9 ni ko'paytirish.
-96=\pi \left(18n-18-2\right)
18 ga n-1 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
-96=\pi \left(18n-20\right)
-20 olish uchun -18 dan 2 ni ayirish.
-96=18\pi n-20\pi
\pi ga 18n-20 ni ko'paytirish orqali distributiv xususiyatdan foydalanish.
18\pi n-20\pi =-96
Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.
18\pi n=-96+20\pi
20\pi ni ikki tarafga qo’shing.
18\pi n=20\pi -96
Tenglama standart shaklda.
\frac{18\pi n}{18\pi }=\frac{20\pi -96}{18\pi }
Ikki tarafini 18\pi ga bo‘ling.
n=\frac{20\pi -96}{18\pi }
18\pi ga bo'lish 18\pi ga ko'paytirishni bekor qiladi.
n=-\frac{16}{3\pi }+\frac{10}{9}
-96+20\pi ni 18\pi ga bo'lish.
