Solve for a (complex solution)
\left\{\begin{matrix}a=\frac{d}{5x}\text{, }&x\neq 0\\a\in \mathrm{C}\text{, }&d=0\text{ and }x=0\end{matrix}\right.
Solve for a
\left\{\begin{matrix}a=\frac{d}{5x}\text{, }&x\neq 0\\a\in \mathrm{R}\text{, }&d=0\text{ and }x=0\end{matrix}\right.
Solve for d
d=5ax

d=xa\times 5
Anything plus zero gives itself.
xa\times 5=d
Swap sides so that all variable terms are on the left hand side.
5xa=d
The equation is in standard form.
\frac{5xa}{5x}=\frac{d}{5x}
Divide both sides by 5x.
a=\frac{d}{5x}
Dividing by 5x undoes the multiplication by 5x.
d=xa\times 5
Anything plus zero gives itself.
xa\times 5=d

5xa=d
The equation is in standard form.
\frac{5xa}{5x}=\frac{d}{5x}
Divide both sides by 5x.
a=\frac{d}{5x}
Dividing by 5x undoes the multiplication by 5x.
d=xa\times 5
Anything plus zero gives itself.
