    Is everyone just to shy to actually admit that they don't know how to solve this, or they might solve it, but not know weather "not solvable" might be the wrong answer?

    Cheers, Hans

    ((2*X + 10)/2) -X = 5
    ((2*(-2) + 10)/2) -(-2) = 5
    ((-4 + 10)/2) +2 = 5
    (6/2) + 2 = 5
    3 + 2 = 5

    X = -2
