In the problem: -(x-5)=2

To get x, first we multiply the negative to the expression (x-5),

thus it becomes:

-x + 5 = 2

then we transpose 5 to the other side leaving x on the other side

-x = 2 - 5

-x = -3

x =3

The answer should have been x = 3

-(x - 5) = 2

-x + 5 = 2;

5 - 2 = x;

x = 3

-x + 5 = 2;

5 - 2 = x;

x = 3
