Solve y/99x-4x^2=0

$$y / 99 x - 4 x ^ { 2 } = 0$$

Solve for y (complex solution)

$$\left\{\begin{matrix}\\y=396x\text{, }&\text{unconditionally}\\y\in \mathrm{C}\text{, }&x=0\end{matrix}\right.$$

Steps for Solving Linear Equation

Multiply both sides of the equation by 99.

$$yx-396x^{2}=0$$

Add 396x^{2} to both sides. Anything plus zero gives itself.

$$yx=396x^{2}$$

The equation is in standard form.

$$xy=396x^{2}$$

Divide both sides by x.

$$\frac{xy}{x}=\frac{396x^{2}}{x}$$

Dividing by x undoes the multiplication by x.

$$y=\frac{396x^{2}}{x}$$

Divide 396x^{2} by x.

$$y=396x$$

Solve for y

$$\left\{\begin{matrix}\\y=396x\text{, }&\text{unconditionally}\\y\in \mathrm{R}\text{, }&x=0\end{matrix}\right.$$
