[quote=vburmester;195468]Hi,
I am stuck on how to solve this:
2x - [3 + (x-5)] = 6
I know the answer if 4, but not how to get it!
If anyone can help, I'd be really grateful.

2x-3-x+5=6 (2x-x=x)
So, x+2=6
x=6-2=4
So, x=4
Always, when before the (..) you have the "minus" sign, the numbers out of the (..), are always with opposite signs.
