The first problem is an ADDITION problem, and you must just combine like terms. This is NOT distributive property.

The second problem you mentioned is the DISTRIBUTIVE PROPERTY. For distributive property, you must have an addition or subtraction within the parentheses, and a product times that sum or difference.
