Solve 4AOD=4x

$$4 A O D = 4 x$$

Solve for A (complex solution)

$$\left\{\begin{matrix}A=\frac{x}{DO}\text{, }&D\neq 0\text{ and }O\neq 0\\A\in \mathrm{C}\text{, }&\left(O=0\text{ or }D=0\right)\text{ and }x=0\end{matrix}\right.$$

Steps for Solving Linear Equation

Cancel out 4 on both sides.

$$AOD=x$$

The equation is in standard form.

$$DOA=x$$

Divide both sides by OD.

$$\frac{DOA}{DO}=\frac{x}{DO}$$

Dividing by OD undoes the multiplication by OD.

$$A=\frac{x}{DO}$$

Solve for D (complex solution)

$$\left\{\begin{matrix}D=\frac{x}{AO}\text{, }&O\neq 0\text{ and }A\neq 0\\D\in \mathrm{C}\text{, }&\left(A=0\text{ or }O=0\right)\text{ and }x=0\end{matrix}\right.$$

Steps for Solving Linear Equation

Cancel out 4 on both sides.

$$AOD=x$$

Divide both sides by AO.

$$\frac{AOD}{AO}=\frac{x}{AO}$$

Dividing by AO undoes the multiplication by AO.

$$D=\frac{x}{AO}$$

Solve for A

$$\left\{\begin{matrix}A=\frac{x}{DO}\text{, }&D\neq 0\text{ and }O\neq 0\\A\in \mathrm{R}\text{, }&\left(O=0\text{ or }D=0\right)\text{ and }x=0\end{matrix}\right.$$
