Question
$$\frac{2}{5}\cdot(18-2^3) = 0$$
Answer
This equation has no solution.
Explanation
$$ \begin{aligned} \frac{2}{5}\cdot(18-2^3) &= 0&& \text{simplify left side} \\[1 em]\frac{2}{5}\cdot(18-8) &= 0&& \\[1 em]\frac{2}{5}\cdot10 &= 0&& \\[1 em]4 &= 0&& \\[1 em] \end{aligned} $$
Since the statement $ \color{red}{ 4 = 0 } $ is FALSE, we conclude that the equation has no solution.
