that depends on what that expression is equal to.
If you are asking what x equals if "-x-2 = 0" for example, then the solution would be:
-x-2 = 0
-x = 2 add 2 to both sides
x = -2 multiply both sides by negative 1 - solved
If, however, -x-2 does NOT equal zero, then this solution is incorrect.
-x - 2 equal to zero, because you found that the value of x is a negative number, x = -2, and the opposite of x is a positive number, -x = -(-2) = 2. Thus -x - 2 = -(-2) - 2 = 2 - 2 = 0
If this is not a maths question, then SE made it X-2 instead of XI because X-2 was a continuation of X, instead a new universe like they usually have when they change the Roman numeral.

Why does x equal to 8 and 0 in x2 equals 8x?
x2 = 8xx2- 8x = 0x(x - 8) = 0x = 0 ;x - 8 = 0x = 8
What is the correct evaluation of x2 plus x - 9 when x is equal to -4?
It is: (-4)^2 +(-4) -9 = 3 when x is equal to -4

What is x squared-7x equals 8 factored?
x2 - 7x = 8 x2 - 7x - 8 = 0Now find two numbers that multiply to equal -8, and add to equal -7.(1) * (-8) = -8(1) + (-8) = -7(x+1)(x-8) = 0 This is the factored form of x2 - 7x = 8You can then solve the equation if necessary, and get:x = -1 or x = +8
