Question

Answer 1

24

Explanation:

Let x be the number of comic books Sandy began with:

`(x)/(2)-2=10\\x-4=20\\x=24`

Therefore, Sandy began with 24 comic books

Answer 2

Answer: 24 comic books

Explanation:

To solve this problem, we first want to define a variable.

Let x=number of books Sandy had originally.

We can create the equation:

`(1)/(2)x-2=10` [add 2 to both sides]

`(1)/(2)x=12` [multiply both sides by 2]

`x=24`

Sandy originally had 24 comic books.
