Let's see it ...

-x+0 + (-x) = 0?

There is a + before the parenthesis, the sign is the same.

-x+0-x = 0

Since the x have equal sign, we add them to get - 2x

We have 2x - 0 = 0

Move the zero to the right, so 2x = 0

Divide both for 2 ...

x = 0

Substitute 0 to x, so - 0+0 + (-0) = 0

0 = 0 the statement is true
