aquad2y-x=7 eching

$$a \quad 2 y - x = 7$$

a_2 uchun yechish (complex solution)

$$\left\{\begin{matrix}a_{2}=\frac{x+7}{y}\text{, }&y\neq 0\\a_{2}\in \mathrm{C}\text{, }&x=-7\text{ and }y=0\end{matrix}\right,$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

x ni ikki tarafga qo’shing.

$$a_{2}y=7+x$$

Tenglama standart shaklda.

$$ya_{2}=x+7$$

Ikki tarafini y ga bo‘ling.

$$\frac{ya_{2}}{y}=\frac{x+7}{y}$$

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

$$a_{2}=\frac{x+7}{y}$$

a_2 uchun yechish

$$\left\{\begin{matrix}a_{2}=\frac{x+7}{y}\text{, }&y\neq 0\\a_{2}\in \mathrm{R}\text{, }&x=-7\text{ and }y=0\end{matrix}\right,$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

x ni ikki tarafga qo’shing.

$$a_{2}y=7+x$$

Tenglama standart shaklda.

$$ya_{2}=x+7$$

Ikki tarafini y ga bo‘ling.

$$\frac{ya_{2}}{y}=\frac{x+7}{y}$$

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

$$a_{2}=\frac{x+7}{y}$$

x uchun yechish

$$x=a_{2}y-7$$

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Ikkala tarafdan a_{2}y ni ayirish.

$$-x=7-a_{2}y$$

Ikki tarafini -1 ga bo‘ling.

$$\frac{-x}{-1}=\frac{7-a_{2}y}{-1}$$

-1 ga bo'lish -1 ga ko'paytirishni bekor qiladi.

$$x=\frac{7-a_{2}y}{-1}$$

7-a_{2}y ni -1 ga bo'lish.

$$x=a_{2}y-7$$
