x+ay=42 eching

$$x + a y = 42$$

a uchun yechish (complex solution)

$$\left\{\begin{matrix}a=-\frac{x-42}{y}\text{, }&y\neq 0\\a\in \mathrm{C}\text{, }&x=42\text{ and }y=0\end{matrix}\right,$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan x ni ayirish.

$$ay=42-x$$

Tenglama standart shaklda.

$$ya=42-x$$

Ikki tarafini y ga bo‘ling.

$$\frac{ya}{y}=\frac{42-x}{y}$$

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

$$a=\frac{42-x}{y}$$

a uchun yechish

$$\left\{\begin{matrix}a=-\frac{x-42}{y}\text{, }&y\neq 0\\a\in \mathrm{R}\text{, }&x=42\text{ and }y=0\end{matrix}\right,$$
