A school question in vectors with a pyramid


I need help with the following problem:

In the attached image, ABCDS is a pyramid whose base is a parallelogram. O is the intersection of the parallelogram diagonals. The following holds:
  • SF = k*SD
  • SE = t*SO

Where k and t are real numbers and SF, SD, SE and SO are vectors in space.

The problem is to express t using k.
