1st step: Is to rewrite the question.
2nd step: Group! Then you find the answer.
Here's another question we worked on. -2n=6
I was stumped on this question, and I think I still am, but im going to try my best to explain.
First of all you CAN'T have a negative 'n'! It's like nothing = something, it's not right!
So, you have to change it to a positive. How? You switch negative 'n' to positive and and change the positive 3 to a negative 3.
"If you have a '-n' that is (-1)n. You must multiply each side by (-1)"
(-1) - n = 5 (-1) and that equals: n = (- 5)
Other than the stuff about changing negative n to positive n, there's one more thing that I almost forgot.
1/2n=5 ..&.. n/2=5 : They are the same thing. Just simplify, it makes it easier!
I'm soo sorry if you guys don't like my scribe post :( It was rushed, I'm soo busy. Please let me know if there's any mistakes, because I know there are many! I, myself don't like my scribe post so I'll update it when I have time. I'm sorry if it didn't meet your expectations... I still need to study it, so I can understand it better.
Well, ANYWAYS .. The next scribe is .... Ben, if you didn't already do one.
GOOD JOB CARRRIEEE! :) Nice pictures. I'm sorry I didn't get to yano. I found your text. Sorry I didn't get to help you. Anyways, you did good explaining the equations, even the ones you had trouble with! Carrie, your scribe is perfect, well done. It doesn't matter HOW it looks like. What matters is that you did it, and you got your message to all the 41 students out there. So, good job :) Keep it up!
