Explanation:

The multiplication property of equality states that if we multiply both sides of an equation by the same non - zero number, the equality still holds. In the given example, to get from $\frac{1}{-3}x = 1$ to $x=-3$, we multiply both sides of the equation by $- 3$. This is an application of the multiplication property of equality.
