calculating the velocity of a reference frame

OK this question has me stumped ...again

well if you have two reference frames S & S' with dimensions x, y, z, t & x', y', z', t' respectively

if you know the values of just x & t' is it even possible to calculate the velocity of the reference frame S' from the perspective of S?

i tried this
V = x/t
V = x/(\lamba)(t' + Vx'/c^2)
then sub in x' as its still unknown
V = x/(\lamba)(t' + V(\lamba)(x - Vt)/c^2)
but now youve just added t back into the equation i seem to just get stuck in an endless loop just making the equation more and more complicated. am i doing it wrong or is it just a trick question?
