-8 < 2x-2 < 0
 
-6 < 2x < 2        [Added 2 to all parts of the inequality]
 
-3 < x < 1         [Divided all parts of the inequality by 2]
 
On the number line, the solution exists between, but not including, -3 and +1.
 
   -4   -3   -2   -1     0     1    2    3    4    5
<--|---o==|==|==|==o---|---|---|---|--->
 
Place open circles at -3 and +1 to indicate that they are not part of the solution.  Darken (I used == marks) the number line between the circles at -3 and +1.  That is the solution.
