To solve for the missing number in the equation \( x + __ - 2 = x - 2 \), we can simplify the equation:
Start with the original equation: \[ x + __ - 2 = x - 2 \]
Subtract \( x \) from both sides: \[ __ - 2 = -2 \]
Now, to isolate the missing number, we can add 2 to both sides: \[ __ = -2 + 2 \] \[ __ = 0 \]
Thus, the number that makes the statement true is 0.
