Solve for b (complex solution)
\left\{\begin{matrix}b=\frac{3a}{x}\text{, }&x\neq 0\\b\in \mathrm{C}\text{, }&a=0\text{ and }x=0\end{matrix}\right.
Solve for a
a=\frac{bx}{3}
Solve for b
\left\{\begin{matrix}b=\frac{3a}{x}\text{, }&x\neq 0\\b\in \mathrm{R}\text{, }&a=0\text{ and }x=0\end{matrix}\right.

bx=a\times 3
Swap sides so that all variable terms are on the left hand side.
xb=3a
The equation is in standard form.
\frac{xb}{x}=\frac{3a}{x}
Divide both sides by x.
b=\frac{3a}{x}
Dividing by x undoes the multiplication by x.
3a=bx
The equation is in standard form.
\frac{3a}{3}=\frac{bx}{3}
Divide both sides by 3.
a=\frac{bx}{3}
Dividing by 3 undoes the multiplication by 3.
