Solve y=2arc

$$y = 2 a r c$$

Solve for a (complex solution)

$$\left\{\begin{matrix}a=\frac{y}{2cr}\text{, }&c\neq 0\text{ and }r\neq 0\\a\in \mathrm{C}\text{, }&\left(r=0\text{ or }c=0\right)\text{ and }y=0\end{matrix}\right.$$

Steps for Solving Linear Equation

Swap sides so that all variable terms are on the left hand side.

$$2arc=y$$

The equation is in standard form.

$$2cra=y$$

Divide both sides by 2rc.

$$\frac{2cra}{2cr}=\frac{y}{2cr}$$

Dividing by 2rc undoes the multiplication by 2rc.

$$a=\frac{y}{2cr}$$

Solve for c (complex solution)

$$\left\{\begin{matrix}c=\frac{y}{2ar}\text{, }&r\neq 0\text{ and }a\neq 0\\c\in \mathrm{C}\text{, }&\left(a=0\text{ or }r=0\right)\text{ and }y=0\end{matrix}\right.$$

Steps for Solving Linear Equation

Swap sides so that all variable terms are on the left hand side.

$$2arc=y$$

Divide both sides by 2ar.

$$\frac{2arc}{2ar}=\frac{y}{2ar}$$

Dividing by 2ar undoes the multiplication by 2ar.

$$c=\frac{y}{2ar}$$

Solve for a

$$\left\{\begin{matrix}a=\frac{y}{2cr}\text{, }&c\neq 0\text{ and }r\neq 0\\a\in \mathrm{R}\text{, }&\left(r=0\text{ or }c=0\right)\text{ and }y=0\end{matrix}\right.$$
