A board of length L feet is cut into two pieces such that the length of piece A is 2 feet less than twice the length of piece B. Which of the following is the length, in feet, of piece A ?
Choose the correct choice from the following answers:  A) (L - 1)/2  B) (2L + 1)/3  C) (L + 1)/3  D) (2L + 2)/3  E) (2L - 2)/3
A+B = L so we know that B = L - A.   A = 2B-2   A = 2(L-A) - 2   3A = 2L - 2   A = (2L-2) / 3   The answer is (2L - 2)/3.
