Answer:
Distributive
Explanations:
The given equation is:
3 (x - 10) = 3x - 30
We can see from the equation that 3 is distributed over x and 10 on the Left Hand Side to give the expression on the Right Hand Side.
The distributive property is of the form:
a ( b + c) = ab + ac
Therefore, the example 3 (x - 10) = 3x - 30 is an example of the distributive property.
