Answers to your questions1. When will you really know if it’s really
simplified?
2. When do you use distributive property?
3. Why would you cancel out the variables from the right instead of the left in distributive property. Why not start with the variable in the left?
4. On hw#5, why do I have to cancel the variable on the right side first rather than the left side first?
