    Question

    If  {1/(y + 1) + 1/(y + 5)} = {1/(y + 2) + 1/(y + 4)}.

    Find the value of y 
    A -3 Correct Answer Incorrect Answer
    B 3 Correct Answer Incorrect Answer
    D -1 Correct Answer Incorrect Answer

    Solution

    We are solving:

    Combine the fractions on both sides. Cancel common terms (2y+6) to get:

    This simplifies to 5=8, which is a contradiction unless 2y+6=0. Solve 2y+6=0: Hence y = -3
