If that's supposed to be a multiplication, the "x" doesn't have a value - it's an operator. The whole expression, on the other hand, does have a value (just do the multiplication).If the "x" is supposed to be an exponent, then it doesn't have a specific value; that is, it may have any value.

The equation 7 times 42 is equal to 294.
In expressions such as "x-y", both "x" and "y" can have any value. The value of "x-y" will depend on what the value of "x" and the value of "y" are.
the value of x is 3
If the reflection is over the x value, the x-value does not change.
zero. The absolute value of a number is just the positive version of that number, so the absolute value of x is x, and x minus x is zero.
That depends what the value of x is.
The answer depends on the value of x, which is not given.
The value of 'x' is 50.
If an expression is true "for no value" of x, it means that there is no value you can substitute for x to make it true. For example, x=x+1 is true for no value of x, because x is always strictly less than x+1.
The domain is the x value
x can have any value in the domain.
