Solve c/A=partialr

$$\frac { c } { A } = \partial r$$

Solve for A

$$\left\{\begin{matrix}A=\frac{c}{r∂}\text{, }&c\neq 0\text{ and }r\neq 0\text{ and }∂\neq 0\\A\neq 0\text{, }&\left(∂=0\text{ or }r=0\right)\text{ and }c=0\end{matrix}\right.$$

Steps for Solving Linear Equation

Variable A cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by A.

$$c=∂rA$$

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

$$∂rA=c$$

The equation is in standard form.

$$r∂A=c$$

Divide both sides by ∂r.

$$\frac{r∂A}{r∂}=\frac{c}{r∂}$$

Dividing by ∂r undoes the multiplication by ∂r.

$$A=\frac{c}{r∂}$$

Variable A cannot be equal to 0.

$$A=\frac{c}{r∂}\text{, }A\neq 0$$

Solve for c

$$c=Ar∂$$

$$A\neq 0$$

Solution Steps

Multiply both sides of the equation by A.

$$c=∂rA$$
