Respuesta :

It is 10 because if you take half of 10 you get 5 and you add nine then get 14

Answer:

Answer: C

Step-by-step explanation:

Let her original number of comic books = x

She sold half of them, so now she has

x - x/2 = x/2

She bought 9 more. That is represented as

x/2 + 9

Her total is 14

x/2 + 9 = 14

Equation

x/2 + 9 = 14 Subtract 9 from both sides.

x/2 = 14 - 9

x/2 = 5         Multiply both sides by 2

x = 5 * 2

x = 10

Originally she had 10 comics.
