<pre><font size = 3><b>
5x - 5 = 2(3x - 1) - 2(x + 3) + 7

5x - 5 =  6x  - 2  -  2x - 6  + 7

5x - 5 =  6x - 2x - 2 - 6 + 7  

5x - 5 =     4x     - 8   + 7

 5x - 5 = 4x - 1
 <u>   + 5      + 5</u>
 5x     = 4x + 4
<u>-4x      -4x</u>____   
  x     =      4 

------------------------------

3x - 2(x + 4) = x + 4x 

  3x - 2x - 8 = 1x + 4x

        x - 8 = 5x
        <u>  + 8      + 8</u>
        x     = 5x + 8
      <u>-5x     =-5x</u>____
      -4x     =      8

      {{{-4x/(-4) = 8/(-4)}}}

           x  =  -2
