Reflexive Property

The step involved here is the Multiplication Property of Equality.

The property applicable to the equation 10y = 10y is the Reflexive Property of Equality. The Reflexive Property states that any quantity is equal to itself.

To understand how the Reflexive Property is applied in this equation, let's break it down step by step:

Step 1: 10y = 10y (Original equation)

At this point, we see that both sides of the equation are exactly the same: 10y. The Reflexive Property allows us to say that a quantity is equal to itself, so we can conclude that 10y is equal to 10y.

Therefore, the answer is Reflexive Property.
