Answer:

The given expressions x+3(7-x) and x+21-3x are equivalent by using the distributive property

Explanation:

Given expressions are x+3(7-x) and x+21-3x and also given that they are equivalent

To find for what property the given two expressions are equivalent :

x+3(7-x)=x+3(7)+3(-x)

=x+21-3x ( here we are using the distributive property a(x+y)=ax+ay )

Therefore the given expressions x+3(7-x) and x+21-3x are equivalent by using the distributive property
