Consider that a linear expression in the first step of simplification shown below which algebraic property was used to simplify the first expression

The property used in the simplification is: Distributive Property.

Step-by-step explanation:

" The distributive property is used to combine the two terms that had the same variable. The distributive property is the key to combining expressions with like terms.

Terms are like terms when they have the exact same variables with the exact same exponents" .

Hence, the property used in the simplification of this expression is a distributive property.
