Rachelle sold half of her comic books and then bought six more. She now has 11. How many did she begin with? Set up the equation and solve it. Include units!

She started with 10.

Equation:

We will be using (c) for comic books.

1/2 (c) + 6=11

Solving it:

1/2 (c) + 6=11

move the 6 over to where the 11 is, making it a - 6.

1/2 (c) = 11-6

(which is 5)

1/2 (c) = 5

now divide by 1/2 to cancel it out and leave us with the (c)

1/2 divided by 1/2 is 1.

5 divided by 1/2 is 10.

c=10

She started with 10 comic books.

Step-by-step explanation:

i think she had 5 to start with. could the equation maybe be n+6=11?
