A board of length L feet is cut into two pieces such that the length of piece A is 3 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 + 3)/3
C) (L + 1)/3
D) (2L + 2)/3
E) (2L - 3)/3
A+B = L so we know that B = L - A.   A = 2B-3   A = 2(L-A) - 3   3A = 2L - 3   A = (2L-3) / 3   The answer is (2L - 3)/3.
