\[\frac{ -2n-2 }{ 3 }=12\] First thing we're gonna do is multiply both sides by 3.

- randomecorner

6/9=36

- 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

sorry was feeding da cat

- randomecorner

so n=36?

- anonymous

You tell me. If you plug 36 in for n in the original equation, will you get 12?

- randomecorner

no nono no

- randomecorner

gah im confused this is why i hate corefocus

- anonymous

\[-2n+(-2+2)=(36+2)\]

- randomecorner

i give up

- anonymous

What is -2+2?

- anonymous

What is 36+2?

- randomecorner

38

- randomecorner

thats a negitive so u sub the 2s

- anonymous

What are you talking about? What is -2+2?

- randomecorner

-4

- randomecorner

srryi was thinking about timesing it

- anonymous

-2+2 is the same as 2-2. 2 minus 2.

- randomecorner

so its not negitive4?
im probably drivingyou crazy sorry

- anonymous

Does 2 minus 2 equal -4?

- randomecorner

no its 0

- anonymous

Then -2+2=0 as well

- anonymous

Sooooooooo\[-2n+0=38\] which is the same as\[-2n=38\]Now just divide both sides by -2.

- randomecorner

32divided by -2 =-16

- anonymous

Where did this 32 come from? We're working with a 38.

- randomecorner

misread srry

- randomecorner

its -19

- randomecorner

i ow u big time

- 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

yep

- anonymous

So that means that -19 is the answer

- randomecorner

sorry i took a lot of time from you

- randomecorner

and probably drove you crazy

- anonymous

It's fine, I've spent longer.

- randomecorner
