1. given a long algebraic equation, what are some strategies that you can use to make simplifying and evaluating the equation more efficient and accurate?
2. how do inverse operations solve algebraic equations? give a real-world scenario where this might be modeled.

1. Use PEMDAS to do the problem in the right order, put like terms together
2. When you plug the value you got back into the equation, you can make sure you found the right value. Construction workers would need to do the inverse to make sure they have the right measurements for the walls
