ae^{x}=x
Variable a cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by a.
e^{x}a=x
The equation is in standard form.
\frac{e^{x}a}{e^{x}}=\frac{x}{e^{x}}
Divide both sides by e^{x}.
a=\frac{x}{e^{x}}
Dividing by e^{x} undoes the multiplication by e^{x}.
a=\frac{x}{e^{x}}\text{, }a\neq 0
Variable a cannot be equal to 0.
