\[\frac{ -2n-2 }{ 3 }=12\] First thing we're gonna do is multiply both sides by 3.
randomecorner
  • randomecorner
6/9=36
anonymous
  • anonymous
The 3's would cancel out. You must have multipled the left side by 3/3, which actually equals 1. It should look like this\[-2n-2=36\] The next step would be to add the 2 on both sides.
randomecorner
  • randomecorner
sorry was feeding da cat
randomecorner
  • randomecorner
so n=36?
anonymous
  • anonymous
You tell me. If you plug 36 in for n in the original equation, will you get 12?
randomecorner
  • randomecorner
no nono no
randomecorner
  • randomecorner
gah im confused this is why i hate corefocus

\[-2n+(-2+2)=(36+2)\]
randomecorner
  • randomecorner
i give up
anonymous
  • anonymous
What is -2+2?
anonymous
  • anonymous
What is 36+2?
randomecorner
  • randomecorner
38
randomecorner
  • randomecorner
thats a negitive so u sub the 2s
anonymous
  • anonymous
What are you talking about? What is -2+2?
randomecorner
  • randomecorner
-4
randomecorner
  • randomecorner
srryi was thinking about timesing it
anonymous
  • anonymous
-2+2 is the same as 2-2. 2 minus 2.
randomecorner
  • randomecorner
so its not negitive4? im probably drivingyou crazy sorry
anonymous
  • anonymous
Does 2 minus 2 equal -4?
randomecorner
  • randomecorner
no its 0
anonymous
  • anonymous
Then -2+2=0 as well
anonymous
  • anonymous
Sooooooooo\[-2n+0=38\] which is the same as\[-2n=38\]Now just divide both sides by -2.
randomecorner
  • randomecorner
32divided by -2 =-16
anonymous
  • anonymous
Where did this 32 come from? We're working with a 38.
randomecorner
  • randomecorner
misread srry
randomecorner
  • randomecorner
its -19
randomecorner
  • randomecorner
i ow u big time
anonymous
  • anonymous
So \[n=-19\] Now all that's left is to plug in -19 for n in the original equation and see if it matches up.
randomecorner
  • randomecorner
yep
anonymous
  • anonymous
So that means that -19 is the answer
randomecorner
  • randomecorner
sorry i took a lot of time from you
randomecorner
  • randomecorner
and probably drove you crazy

  • randomecorner
i think that was a hour

We spent 25 minutes.
