1. Given - this is the original equation given that we want to solve
2. Distributive Property - when multiplying a one thing by something else, we can multiply through by the first thing (a constant in this case) to each term within the second something (in parenthesis)
3. Subtraction Property of Equality - if we subtract the same thing from both sides of the equation, it stays equivalent
4. Division Property of Equality - if we divide both sides of the equation by the same thing, it stays equivalent
