Since, you have not told what the expression -x equals to. So, I am assuming the expression -x is equal to zero. i.e. -x = 0 to make it an equation to determine the value of x.
Answer:
The value of x is zero i.e. x= 0 in the equation -x = 0.
The graph of the equation -x = 0 is also attached.
Explanation:
As we know that an equation is a mathematical sentence which has two equal sides. These two equal side separated by an '=' sign - often called equal sign.
For example, 3 + 8 = 11 is an example of an equation.
Now, considering the expression
-x
Let us determine the value of x by equaling the expression to zero.
i.e.
-x = 0
so lets solve -x = 0
considering the equation
Therefore, the value of x is zero i.e. x= 0 in the equation -x = 0.
The graph of the equation -x = 0 is also attached.
