xy-y=d+xb eching

$$x y - y = d + x b$$

b uchun yechish (complex solution)

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

Chiziqli tenglamalarni yechish bo'yicha qadamlar

Tomonlarni almashtirib, barcha oʻzgaruvchi shartlar chap tomonga oʻtkazing.

$$d+xb=xy-y$$

Ikkala tarafdan d ni ayirish.

$$xb=xy-y-d$$

Ikki tarafini x ga bo‘ling.

$$\frac{xb}{x}=\frac{xy-y-d}{x}$$

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

$$b=\frac{xy-y-d}{x}$$

b uchun yechish

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