Answer:

14

Step-by-step explanation:

You just multiply 2 to (x + 7) which gets you 2x + 14 and then subtract 2x from 2x seeing as they are like terms and you end up with 14.

14

Multiply 2 by both x and 7. That will get you 2x+14-2x. Then to combine like terms add the negative 2x and the positive 2x which cancel out. For a final answer you get 14.
