Solve fv=-2x-9

$$f v = - 2 x - 9$$

Solve for f (complex solution)

$$\left\{\begin{matrix}f=-\frac{2x+9}{v}\text{, }&v\neq 0\\f\in \mathrm{C}\text{, }&x=-\frac{9}{2}\text{ and }v=0\end{matrix}\right.$$

Steps for Solving Linear Equation

The equation is in standard form.

$$vf=-2x-9$$

Divide both sides by v.

$$\frac{vf}{v}=\frac{-2x-9}{v}$$

Dividing by v undoes the multiplication by v.

$$f=\frac{-2x-9}{v}$$

Divide -2x-9 by v.

$$f=-\frac{2x+9}{v}$$

Solve for v (complex solution)

$$\left\{\begin{matrix}v=-\frac{2x+9}{f}\text{, }&f\neq 0\\v\in \mathrm{C}\text{, }&x=-\frac{9}{2}\text{ and }f=0\end{matrix}\right.$$
