Solve for x: 12 = x + 2(3)
This is a two-step equation. First and foremost - remember PEMDAS. Always start with parenthesis, then see if there are exponents. Once you have those taken care of, solve any multiplication or division (working left to right) followed by any addition and subtraction (again, working left to right). In this problem we have parenthesis - so that is where we will start. 2(3) is the same as 2 * 3 or 2 times 3. 2 times 3 is 6. Now, our problem is 12 = x + 6. Since we need to isolate the variable, x in this case, the next step is to move the 6 to the other side of the equation... the other side of the equals sign. To do this, we need to do the opposite. Since this is a positive 6 (there is also a plus sign before the 6) we are going to subtract the 6 from both sides. It will look something like this... 12 = x + 6 -6 - 6 12 - 6 is 6. We are now left is 6 = x. That's it! x is 6. Lets double check out work by plugging 6 back into the original equation. 12 = 6 + 2(3) 6 12 = 6 + 6 12 = 12 Awesome!

When it comes to planning for a long-term project, what are some important things to consider?
Long-term projects can be difficult for many people. Often times, people find it difficult breaking down what specific tasks need to be completed, time frames in which these individual tasks should be completed and avoiding procrastinating these tasks. While larger long-term projects can be overwhelming, breaking them down into smaller and more manageable tasks can be a helpful strategy. For example, if you have a presentation due in a month that requires a Powerpoint presentation as well as an interactive activity, it is important to break down everything that needs to be accomplished in order to reach that final goal - the presentation itself. Do you need to gather information? Do you need to conduct interviews? Are there any materials you need to gather and bring to the presentation? These are all important things to consider and can be very helpful to plan ahead for, and in doing so you will find that projects like this are far less daunting and rather manageable.

What are some primary factors that lead humans to settle in or close to urban centers?
Over thousands of years humans have increasingly found convenience in living close to an urban center. Urban centers are not always what we think of today - they do not necessarily have tall buildings, congested traffic and dense populations. There are many factors that have contributed to the development of urban centers such as a central location to trade. Often times, food was grown or animals were raised in rural areas outside of these urban centers. When it came to trading or selling these goods, humans traveled into these central locations, which over time turned into urban centers, to do so. While there are many contributing factors that led to the urbanization of our civilizations, one of the driving factors was the need to trade goods (food, livestock, etc.).
