Let \overline{a}=\overline{i}+2 \overline{j}+3 \overline{k}, \overline{b}=2 \overline{i}-3 \overline{j}+\overline{k} and \overline{c}=3 \overline{i}+\overline{j}-2 \overline{k} be three vectors. If \overline{ {\r}} is a vector such that \overline{ {\r}} \cdot \overline{a}=0, \overline{ {\r}} \cdot \overline{b}=-2 and \overline{ {\r}} \cdot \overline{c}=6 then \overline{ {\r}} \cdot(3 \overline{i}+\overline{j}+\overline{k})=
