Question

Jon's sock drawer has 6 fewer black sock than twice as many "w" white socks. Write an expression for the total number of black socks

Answer 1

Let b = number of black socks

 

2w - b = 6

 

this means that twice the number white socks is greater than black socks by 6.  In the same way, the number of black socks is fewer than twice the number of white socks by 6.

 

 

Now solve for b from this equation. 

 

b = 2w - 6
