fy=-3x+13 eching

$$f y = - 3 x + 13$$

f uchun yechish (complex solution)

$$\left\{\begin{matrix}f=-\frac{3x-13}{y}\text{, }&y\neq 0\\f\in \mathrm{C}\text{, }&x=\frac{13}{3}\text{ and }y=0\end{matrix}\right,$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tenglama standart shaklda.

$$yf=13-3x$$

Ikki tarafini y ga bo‘ling.

$$\frac{yf}{y}=\frac{13-3x}{y}$$

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

$$f=\frac{13-3x}{y}$$

f uchun yechish

$$\left\{\begin{matrix}f=-\frac{3x-13}{y}\text{, }&y\neq 0\\f\in \mathrm{R}\text{, }&x=\frac{13}{3}\text{ and }y=0\end{matrix}\right,$$

x uchun yechish

$$x=\frac{13-fy}{3}$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$-3x+13=fy$$

Ikkala tarafdan 13 ni ayirish.

$$-3x=fy-13$$

Ikki tarafini -3 ga bo‘ling.

$$\frac{-3x}{-3}=\frac{fy-13}{-3}$$

-3 ga bo'lish -3 ga ko'paytirishni bekor qiladi.

$$x=\frac{fy-13}{-3}$$

fy-13 ni -3 ga bo'lish.

$$x=\frac{13-fy}{3}$$
