-(x-4)
= -x + 4
= -x + 4
-(x-4) can be expanded as -x + 4. By applying the distributive property, the negative sign is multiplied to every term inside the parentheses. The negative sign in front of the parentheses changes the sign of both terms inside, resulting in -x and -4.
So, the simplified form of -(x-4) is -x + 4.
