Question
$$-3 \cdot \frac{-\frac{16}{4}}{4} = 0$$
Answer
This equation has no solution.
Explanation
$$ \begin{aligned} -3 \cdot \frac{-\frac{16}{4}}{4} &= 0&& \text{simplify left side} \\[1 em]-3\cdot\frac{-1}{1} &= 0&& \\[1 em]-3(-\frac{1}{1}) &= 0&& \\[1 em]-3\cdot(-1) &= 0&& \\[1 em]3 &= 0&& \\[1 em] \end{aligned} $$
Since the statement $ \color{red}{ 3 = 0 } $ is FALSE, we conclude that the equation has no solution.
