Solve y=ab^3x

$$y = a b ^ { 3 x }$$

Solve for a (complex solution)

$$\left\{\begin{matrix}a=\frac{y}{b^{3x}}\text{, }&x=0\text{ or }b\neq 0\\a\in \mathrm{C}\text{, }&y=0\text{ and }b=0\text{ and }x\neq 0\end{matrix}\right.$$

Steps for Solving Linear Equation

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

$$ab^{3x}=y$$

The equation is in standard form.

$$b^{3x}a=y$$

Divide both sides by b^{3x}.

$$\frac{b^{3x}a}{b^{3x}}=\frac{y}{b^{3x}}$$

Dividing by b^{3x} undoes the multiplication by b^{3x}.

$$a=\frac{y}{b^{3x}}$$

Solve for a

$$\left\{\begin{matrix}a=\frac{y}{b^{3x}}\text{, }&b>0\text{ or }\left(Denominator(3x)\text{bmod}2=1\text{ and }b<0\right)\\a\in \mathrm{R}\text{, }&y=0\text{ and }b=0\text{ and }x>0\end{matrix}\right.$$
