This week, I was away from a lesson we did. After asking a few people, none seemed to have any notes. One of the many things that I learned this week, is that you can ask Mrs. Burton for the notes, if you can’t find any. Because of this, I was very confused for this lesson on how to do anything. One of the things I was most confused with though, was solving an equation. To better understand how, the “gift” technique.
For this equation, the seven is in front of the root. This can be thought of as a bow on top of a gift, you need to take it off before you can “open” any of the rest of the equation. To do this, you have to divide both sides by seven to get rid of it. Next, you have to get rid of the root or the “wrappping”. To do this, you have to square both sides. After you have done this, you have one last step to get to the “gift” (to isolate x). You have to get rid of the number that is next to the x. To do this, you divide both sides by two (or the number that is there). And this will give you your gift, or your answer.
