Question
$$-5\cdot3+(-10)-9\cdot(-1) = 0$$
Answer
This equation has no solution.
Explanation
$$ \begin{aligned} -5\cdot3+(-10)-9\cdot(-1) &= 0&& \text{simplify left side} \\[1 em]-15-10+9 &= 0&& \\[1 em]-16 &= 0&& \\[1 em] \end{aligned} $$
Since the statement $ \color{red}{ -16 = 0 } $ is FALSE, we conclude that the equation has no solution.
