Solve y=operatorname{arc}

$$y = \operatorname { arc }$$

Solve for a

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

Steps for Solving Linear Equation

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

$$arc=y$$

The equation is in standard form.

$$cra=y$$

Divide both sides by rc.

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

Dividing by rc undoes the multiplication by rc.

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

Solve for c

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

Steps for Solving Linear Equation

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

$$arc=y$$

Divide both sides by ar.

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

Dividing by ar undoes the multiplication by ar.

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