and 
have the variable 
, so we can subtract them.
When subtracting these terms, we subtract the coefficients and keep the variable.
So:

Answer:
-2x - 6
Step-by-step explanation:
-2(x + 3)

If, instead, you actually moved on a straight line from point A to point B, then the two quantities are the same.
