1. The problem statement, all variables and given/known data
We normally assume that the origins of two inertial frames coincide at t=t'=0. This way we find:
t' = γ(t - vx/c2)
x' = γ(x-vt)

Suppose instead that when t=T the origin of S' (which is moving along the x-x' axis with speed v relative to S) has abscissa x=X (neglect y and z) and the S' clock at the origin of S' reads t'=0 at that moment.

a. How do the Lorentz transformations from S to S' need to be modified?
b. What about from S' to S?
c. Write these in matrix form.

Hint: you do not need to re-derive these transformations, try introducing an auxiliary frame that reduces the problem to the usual case.

2. Relevant equations
Lorentz transformations (above)

3. The attempt at a solution

I don't know how to start this problem...
