$$x$$ could be -1, -2, -3, etc., and postives are a whole bunch.

Let's get solving the expression (I think)!

let's substitute $$x$$ into 1.

Now, rewrite the expression.

$$-2-x>5\Rightarrow-2-1>5$$

Now, subtract.

$$-2-1=-3$$

Now, combine the expression.

$$-3>5$$

Because this is false, let's continue.

Now, change $$x$$ into -10.

$$-2-x>5\Rightarrow-2-(-10)>5$$

Now, solve.

$$\\\\-2-(-10)=-2+(10)\\\\=8$$

Now, combine the expression.

$$8>5$$

This makes the expression true, so one answer can be $$\boxed{8>5}$$.
