This expression doesn't tell what 'x' has to be. In fact, 'x' can be anything. Your choice.

Every time you change 'x', the expression becomes a different number.

If this expression were equal to something, then we could get some exercise

figuring out what 'x' must be in order to make the equation true. But in its present

form, it doesn't say anything, so there's nothing to be proven true or false. It's just

a number that depends on what 'x' is.
