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.
