Consider to distribute to every term inside the parentheses.
Distributive Property
Practice makes perfect
To identify the Property of Equality being demonstrated by the given equations, we should first identify the operation being performed.
If x(y+z)=4, then xy+xz=4.
In this case, the product of a number and a parenthetical factor is equal to the sum of the products of the number and each term inside the parentheses. This is the Distributive Property.
