PA+PB=2I eching

$$P A + P B = 2 I$$

A uchun yechish

$$\left\{\begin{matrix}A=-B+\frac{2I}{P}\text{, }&P\neq 0\\A\in \mathrm{R}\text{, }&I=0\text{ and }P=0\end{matrix}\right,$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan PB ni ayirish.

$$PA=2I-PB$$

Tenglama standart shaklda.

$$PA=2I-BP$$

Ikki tarafini P ga bo‘ling.

$$\frac{PA}{P}=\frac{2I-BP}{P}$$

P ga bo'lish P ga ko'paytirishni bekor qiladi.

$$A=\frac{2I-BP}{P}$$

2I-PB ni P ga bo'lish.

$$A=-B+\frac{2I}{P}$$

B uchun yechish

$$\left\{\begin{matrix}B=-A+\frac{2I}{P}\text{, }&P\neq 0\\B\in \mathrm{R}\text{, }&I=0\text{ and }P=0\end{matrix}\right,$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan PA ni ayirish.

$$PB=2I-PA$$

Tenglama standart shaklda.

$$PB=2I-AP$$

Ikki tarafini P ga bo‘ling.

$$\frac{PB}{P}=\frac{2I-AP}{P}$$

P ga bo'lish P ga ko'paytirishni bekor qiladi.

$$B=\frac{2I-AP}{P}$$

2I-PA ni P ga bo'lish.

$$B=-A+\frac{2I}{P}$$
