Answer
symmetric property of equality
Work Step by Step
The symmetric property says that if a=b, then b=a. In other words, it does not matter which term is to the right of the equal sign and which is to the left. If two terms are equal, they are equal in either order.
$3.8=n$ and $n=3.8$ are two equations with the same expressions in a different order. This is an example of the symmetric property of equality.
