Question

Benny sold half of his comics book and then bought 7 more. He now has 12. How many did he began with?

Answer 1

we can write the equation as

x/2 + 7 = 12

x/2 = 12 - 7

x/2 = 5

x = 5 X 2

x= 10

Answer 2

Hi,


Here are the equations:

$12 - 7 = 5 \\ 5 \times 2 = 10$

He started with 10 comic books.

Hope this helps.
