 This bootcamp takes you through several mathematical concepts and techniques that you need in order to do the introduction to statistics course. Okay, here we have one equation, one unknown, okay? Two equals x minus three divided by four. What you got to do is multiply both sides by four. Now you'll have eight equals x minus three. Now you got to bring the three over to the other side, so you add three to both sides. So now you have eight plus three equals x minus three plus three, which is just x. X equals 11. Okay, and this probably have minus five equals x minus six divided by seven, okay? Multiply both sides by seven. Now you have x minus six on the right and minus 35 on the left. Add six to both sides. So now you have minus 29 equals x. To find more bootcamp modules, visit the stat course at the URL you see there and go to the navigation bar on the left, click bootcamp, and you'll see all kinds of things that are good to do prior to the statistics course. Many of you have already done this before and maybe only need a refresher.
