What value will make these two vectors parallel?

[kasda-1]

Homework Statement

What value of c will make these two vectors parallel?

Homework Equations

3i + 2j + 9k = w
5i - j + ck = v

The Attempt at a Solution

I tried too find a common factor to multiply by the w vector to get the components of the v vector, but no luck.

3i (5/3) + 2j (5/3) +9k (5/3) = 5i + 10/3 j + 45/3 k ≠ 5i - j +ck

Would that lead you to conclude that there is no value of c that will make them parallel? Because that would be correct.

I thought and thought about this problem, wondering if this is a trick question. It probably is that simple :).
