Datrys 7x-5y(x+36y)=7

$$7x-5y(x+36y)=7$$

Datrys ar gyfer x

$$x=\frac{180y^{2}+7}{7-5y}$$

$$y\neq \frac{7}{5}$$

Camau ar gyfer Datrys Hafaliad Llinol

Lluosi -1 a 5 i gael -5.

$$7x-5y\left(x+36y\right)=7$$

Defnyddio’r briodwedd ddosbarthu i luosi -5y â x+36y.

$$7x-5yx-180y^{2}=7$$

Ychwanegu 180y^{2} at y ddwy ochr.

$$7x-5yx=7+180y^{2}$$

Cyfuno pob term sy'n cynnwys x.

$$\left(7-5y\right)x=7+180y^{2}$$

Mae'r hafaliad yn y ffurf safonol.

$$\left(7-5y\right)x=180y^{2}+7$$

Rhannu’r ddwy ochr â -5y+7.

$$\frac{\left(7-5y\right)x}{7-5y}=\frac{180y^{2}+7}{7-5y}$$

Mae rhannu â -5y+7 yn dad-wneud lluosi â -5y+7.

$$x=\frac{180y^{2}+7}{7-5y}$$

Datrys ar gyfer y (complex solution)

$$y=\frac{\sqrt{25x^{2}+5040x-5040}}{360}-\frac{x}{72}$$

$$y=-\frac{\sqrt{25x^{2}+5040x-5040}}{360}-\frac{x}{72}$$

Datrys ar gyfer y

$$y=\frac{\sqrt{25x^{2}+5040x-5040}}{360}-\frac{x}{72}$$

$$y=-\frac{\sqrt{25x^{2}+5040x-5040}}{360}-\frac{x}{72}\text{, }x\geq \frac{12\sqrt{1799}-504}{5}\text{ or }x\leq \frac{-12\sqrt{1799}-504}{5}$$
