7 - 2[2x-2]+x-8=6
=> 7 - 4x + 4 +x -8 =6
=> 3 - 3x=6
=> x=-1

7-2[4-(6-2x)] - (8- x) =6 - Original equation
7-2[4-6+2x] - 8+x=6 - multiply or distribute into parenthesis
7-2[-2+2x] -8+x=6 - add/sub within brackets
7+4-4x-8+x=6 - disribute into brackets
3-3x=6 - Collect like terms
-3x=3 - - the three to both sides
x=-1 - divide by -3 on both sides

7-2[4 - 6 + 2x] - 8 + x = 6
7 - 2 (-2+2x) -8 +x = 6
7 + 4 - 4x - 8 + x = 6
3 - 3x = 6
3x = -3
x= -1

7-2[4 - (6-2x) ] - (8-x) = 6
7- [8-(12-4x)] - (8-x) =6
7- [8+-12 +4x] - (8-x)=6
7-[-4 +4x] - (8-x)=6
7+ 4 - 4x -8 +x =6
-3x=3
x=-1
