2r+2pirθ/36q=50 eching

$$2 r + \frac { 2 \pi r \theta } { 36 q } = 50$$

q uchun yechish

$$\left\{\begin{matrix}q=-\frac{\pi r\theta }{36\left(r-25\right)}\text{, }&\theta \neq 0\text{ and }r\neq 0\text{ and }r\neq 25\\q\neq 0\text{, }&r=25\text{ and }\theta =0\end{matrix}\right,$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

q qiymati 0 teng bo‘lmaydi, chunki nolga bo‘lish mumkin emas. Tenglamaning ikkala tarafini 36q ga ko'paytirish.

$$2r\times 36q+2\pi r\theta =1800q$$

72 hosil qilish uchun 2 va 36 ni ko'paytirish.

$$72rq+2\pi r\theta =1800q$$

Ikkala tarafdan 1800q ni ayirish.

$$72rq+2\pi r\theta -1800q=0$$

Ikkala tarafdan 2\pi r\theta ni ayirish. Har qanday sonni noldan ayirsangiz, o‘zining manfiyi chiqadi.

$$72rq-1800q=-2\pi r\theta$$

q'ga ega bo'lgan barcha shartlarni birlashtirish.

$$\left(72r-1800\right)q=-2\pi r\theta$$

Ikki tarafini 72r-1800 ga bo‘ling.

$$\frac{\left(72r-1800\right)q}{72r-1800}=-\frac{2\pi r\theta }{72r-1800}$$

72r-1800 ga bo'lish 72r-1800 ga ko'paytirishni bekor qiladi.

$$q=-\frac{2\pi r\theta }{72r-1800}$$

-2\pi r\theta ni 72r-1800 ga bo'lish.

$$q=-\frac{\pi r\theta }{36\left(r-25\right)}$$

q qiymati 0 teng bo‘lmaydi.

$$q=-\frac{\pi r\theta }{36\left(r-25\right)}\text{, }q\neq 0$$

r uchun yechish

$$r=\frac{900q}{36q+\pi \theta }$$

$$\theta \neq -\frac{36q}{\pi }\text{ and }q\neq 0$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tenglamaning ikkala tarafini 36q ga ko'paytirish.

$$2r\times 36q+2\pi r\theta =1800q$$

72 hosil qilish uchun 2 va 36 ni ko'paytirish.

$$72rq+2\pi r\theta =1800q$$

r'ga ega bo'lgan barcha shartlarni birlashtirish.

$$\left(72q+2\pi \theta \right)r=1800q$$

Ikki tarafini 72q+2\pi \theta ga bo‘ling.

$$\frac{\left(72q+2\pi \theta \right)r}{72q+2\pi \theta }=\frac{1800q}{72q+2\pi \theta }$$

72q+2\pi \theta ga bo'lish 72q+2\pi \theta ga ko'paytirishni bekor qiladi.

$$r=\frac{1800q}{72q+2\pi \theta }$$

1800q ni 72q+2\pi \theta ga bo'lish.

$$r=\frac{900q}{36q+\pi \theta }$$
