Here are the essential concepts you must grasp in order to answer the question correctly.
Distributive Property
The distributive property states that a(b + c) = ab + ac. This property allows us to multiply a single term by two or more terms inside parentheses, effectively distributing the multiplication across the terms. It is essential for simplifying expressions and solving equations in algebra.

Combining Like Terms
Combining like terms involves adding or subtracting terms that have the same variable raised to the same power. This process simplifies expressions by consolidating similar terms into a single term, making calculations easier and clearer. For example, in the expression 7r - 9r, both terms are like terms and can be combined.
