Suppose vectors A,B & C are <5,3>, <1,2> and <3,-2> respectively.
Then 6A = <30,18>
-2B = <-2,-4> and
-3C = <-9,6>.
then r = <sum of all first components,sum of all second components>,
namely <19,20>

Assuming vectors in 3 dimensions,
A = Axi + Ayj + Azk
B = Bxi + Byj + Bzk
C = Cxi + Cyj + Czk
6A - 2B - 3C = (6Ax - 2Bx - 3Cx)i + (6Ay - 2By - 3Cy)j + (6Az - 2Bz - 3Cz)k
