To subtract the polynomials $2x - 4$ and $x - 5$, follow these steps:

1. Write down the polynomials:
   $(2x - 4) - (x - 5)$

2. Distribute the negative sign to the second polynomial:
   $2x - 4 - x + 5$

3. Combine like terms (terms with $x$ and constant terms separately):

   • Combine $2x - x = x$
   • Combine $-4 + 5 = 1$

So, the result is:

$x + 1$
