Solve v=flambda

$$v = f \lambda$$

Solve for f

$$\left\{\begin{matrix}f=\frac{v}{\lambda }\text{, }&\lambda \neq 0\\f\in \mathrm{R}\text{, }&v=0\text{ and }\lambda =0\end{matrix}\right.$$

Steps for Solving Linear Equation

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

$$f\lambda =v$$

The equation is in standard form.

$$\lambda f=v$$

Divide both sides by \lambda .

$$\frac{\lambda f}{\lambda }=\frac{v}{\lambda }$$

Dividing by \lambda undoes the multiplication by \lambda .

$$f=\frac{v}{\lambda }$$

Solve for v

$$v=f\lambda$$
