When you have a negative sign before a parenthesis, it should be treated like a negative one (-1).
-(5x + 2) + 2(1 + 5x) Given
-5x - 2 + 2 + 10x Distributive property (the numbers in the 1st parenthesis times -1)
-5x + 10x -2 + 2 Commutative property
5x + 0 Simplify
5x Identity property of addition
Yes, it's like multiplying whatever follows by negative one.
Or, it's your permission to erase the parenthsis and just flip the sign of everything that was inside them.

Whenever you come across a negative that's not immediately attached to a number or variable, you can safely put a 1 next to it to make it a -1. In your situation that -1 would the distributed in as John has shown below.
