l^{-},m^{-},n^{-} are three unit vectors in a right handed system and L is a line through the points A, B, C whose position vectors are pl^{-}+7m^{-}-6n^{-}, 2l^{-}+5m^{-}-4n^{-} and l^{-}+4m^{-}-3n^{-} respectively. If the equation of the plane containing L and the point (-p,p,p+1) is ax+by+cz=1, then (a+b+c)=
