Solve X%text{de}95=4.A

$$X \% \text { de } 95 = 4 . A$$

Solve for A

$$A=\frac{19eXd}{80}$$

Steps for Solving Linear Equation

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

$$4A=de\times 95\times X\%$$

The equation is in standard form.

$$4A=95ed\times X\%$$

Divide both sides by 4.

$$\frac{4A}{4}=\frac{19eXd}{4\times 20}$$

Dividing by 4 undoes the multiplication by 4.

$$A=\frac{19eXd}{4\times 20}$$

Divide \frac{19deX}{20} by 4.

$$A=\frac{19eXd}{80}$$

Solve for X (complex solution)

$$\left\{\begin{matrix}X=\frac{80A}{19ed}\text{, }&d\neq 0\\X\in \mathrm{C}\text{, }&A=0\text{ and }d=0\end{matrix}\right.$$

Solve for X

$$\left\{\begin{matrix}X=\frac{80A}{19ed}\text{, }&d\neq 0\\X\in \mathrm{R}\text{, }&A=0\text{ and }d=0\end{matrix}\right.$$
