ANSWER
The Multiplicative Property of Equality
EXPLANATION
The Multiplicative Property of Equality allows us to multiply both sides of the given equation by the same quantity.
So for the given equation,
[tex]\frac{x}{5}=2[/tex]
When we multiply both sides by 5, we get;
[tex]5\times \frac{x}{5}=2\times 5[/tex]
[tex]\Rightarrow x=10[/tex]
