P(13)quadr:2x-3y+1=0 eching

$$P ( 13 ) \quad r : 2 x - 3 y + 1 = 0$$

P uchun yechish

$$\left\{\begin{matrix}P=-\frac{2\left(1-3y\right)}{13rx}\text{, }&x\neq 0\text{ and }r\neq 0\\P\in \mathrm{R}\text{, }&\left(r=0\text{ or }x=0\right)\text{ and }y=\frac{1}{3}\end{matrix}\right,$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tenglamaning ikkala tarafini 2 ga ko'paytirish.

$$P\times 13rx-6y+2=0$$

6y ni ikki tarafga qo’shing. Har qanday songa nolni qo‘shsangiz, o‘zi chiqadi.

$$P\times 13rx+2=6y$$

Ikkala tarafdan 2 ni ayirish.

$$P\times 13rx=6y-2$$

Tenglama standart shaklda.

$$13rxP=6y-2$$

Ikki tarafini 13rx ga bo‘ling.

$$\frac{13rxP}{13rx}=\frac{6y-2}{13rx}$$

13rx ga bo'lish 13rx ga ko'paytirishni bekor qiladi.

$$P=\frac{6y-2}{13rx}$$

6y-2 ni 13rx ga bo'lish.

$$P=\frac{2\left(3y-1\right)}{13rx}$$

r uchun yechish

$$\left\{\begin{matrix}r=-\frac{2\left(1-3y\right)}{13Px}\text{, }&x\neq 0\text{ and }P\neq 0\\r\in \mathrm{R}\text{, }&\left(P=0\text{ or }x=0\right)\text{ and }y=\frac{1}{3}\end{matrix}\right,$$

$$r=\frac{6y-2}{13Px}$$

6y-2 ni 13Px ga bo'lish.

$$r=\frac{2\left(3y-1\right)}{13Px}$$
