1. The problem statement, all variables and given/known data X divides a line segment (AB) in a ratio of 3:4. Y divides line segment AX in a ratio of 1:2. If K is any point of the line containing A,B,X and Y; Please show that AY= 1/7OB - 1/7OA 2. Relevant equations Not sure if any. Just adding and subtracting vectors. 3. The attempt at a solution Alright so I know that 1/4 AB +BO would equal XO, but i don't know what do next. Thanks for the help.
