WTF?

x - { 4 - { x - 4 -x } } = 6
x - { 4 + 4 } = 6
x - 8 = 6
x = 14

You've typed this in incorrectly. I assume that the second { is supposed to be a [.
You just start working from the inside to the outside
x-{4-[x-(4 + x)]} = 6
x-{4-[x-4 - x]} = 6
x-{4-[-4]} = 6
x-{4+4} = 6
x - 8 = 6
x = 14

It may be 'complicated', but it is -not- 'complex' (since it doesn't involve complex-valued variables)
Just simplify it from the inside out
x-{4-[x-(4+x)]}=6
x-{4-[x-4-x]}=6
x-{4-[-4])=6
x-{4+4}=6
x-8=6
x=14
