Solve I=rho_{r}t

$$I = \rho _ { r } t$$

Solve for t (complex solution)

$$\left\{\begin{matrix}t=\frac{I}{\rho _{r}}\text{, }&\rho _{r}\neq 0\\t\in \mathrm{C}\text{, }&I=0\text{ and }\rho _{r}=0\end{matrix}\right.$$

Steps for Solving Linear Equation

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

$$\rho _{r}t=I$$

Divide both sides by \rho _{r}.

$$\frac{\rho _{r}t}{\rho _{r}}=\frac{I}{\rho _{r}}$$

Dividing by \rho _{r} undoes the multiplication by \rho _{r}.

$$t=\frac{I}{\rho _{r}}$$

Solve for t

$$\left\{\begin{matrix}t=\frac{I}{\rho _{r}}\text{, }&\rho _{r}\neq 0\\t\in \mathrm{R}\text{, }&I=0\text{ and }\rho _{r}=0\end{matrix}\right.$$

Solve for I

$$I=t\rho _{r}$$
