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

    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.

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

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

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

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

    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.
