Lahenda x/y+z/y+2(x+z)=10x+y

$$\frac{ x }{ y } + \frac{ z }{ y } +2(x+z)=10x+y$$

Lahendage ja leidke x (complex solution)

$$\left\{\begin{matrix}x=-\frac{z+2yz-y^{2}}{1-8y}\text{, }&y\neq \frac{1}{8}\text{ and }y\neq 0\\x\in \mathrm{C}\text{, }&y=\frac{1}{8}\text{ and }z=\frac{1}{80}\end{matrix}\right,$$

Juhised lineaarvõrrandi lahendamiseks

Korrutage võrrandi mõlemad pooled y-ga.

$$x+z+2\left(x+z\right)y=10xy+yy$$

Korrutage y ja y, et leida y^{2}.

$$x+z+2\left(x+z\right)y=10xy+y^{2}$$

Kasutage distributiivsusomadust, et korrutada 2 ja x+z.

$$x+z+\left(2x+2z\right)y=10xy+y^{2}$$

Kasutage distributiivsusomadust, et korrutada 2x+2z ja y.

$$x+z+2xy+2zy=10xy+y^{2}$$

Lahutage mõlemast poolest 10xy.

$$x+z+2xy+2zy-10xy=y^{2}$$

Kombineerige 2xy ja -10xy, et leida -8xy.

$$x+z-8xy+2zy=y^{2}$$

Lahutage mõlemast poolest z.

$$x-8xy+2zy=y^{2}-z$$

Lahutage mõlemast poolest 2zy.

$$x-8xy=y^{2}-z-2zy$$

Kombineerige kõik liikmed, mis sisaldavad x.

$$\left(1-8y\right)x=y^{2}-z-2zy$$

Võrrand on standardkujul.

$$\left(1-8y\right)x=y^{2}-2yz-z$$

Jagage mõlemad pooled -8y+1-ga.

$$\frac{\left(1-8y\right)x}{1-8y}=\frac{y^{2}-2yz-z}{1-8y}$$

-8y+1-ga jagamine võtab -8y+1-ga korrutamise tagasi.

$$x=\frac{y^{2}-2yz-z}{1-8y}$$

Lahendage ja leidke x

$$\left\{\begin{matrix}x=-\frac{z+2yz-y^{2}}{1-8y}\text{, }&y\neq \frac{1}{8}\text{ and }y\neq 0\\x\in \mathrm{R}\text{, }&y=\frac{1}{8}\text{ and }z=\frac{1}{80}\end{matrix}\right,$$
