What is a book sock and why are you posting a mathematical question on Books and Authors?

Asker, it's your responsibility to check that Yahoo has posted your question in the right category. Obviously this isn't the right one, so please move your question to 'Homework help' or 'Maths'.

EDIT TO ADD: I too am curious to know what a 'book sock' might be.

What is a 'book sock' and why is this in the Books & Authors section?

Book socks are regular socks that one wears when reading books. These socks are generally used only when one is  reading books.

Let regular socks = a

Let jumbo socks = b

a + b = 11

\$2a + \$3b = \$26

Multiply eq'n 1 by -3

-3a - 3b = -33

2a + 3b = 26

-a = -7

a = 7

Pedro bought 7 regular socks.
