- Two frames S and S'. Does it matter if S' is moving to the right or to the left of S?

Two simple equations, yet I can't find any sources that explains it very well. If you have any suggestions on where I could find this then please link them! $$ \Delta{t'}=\gamma(\Delta{t}-\frac{v}{c^2}\Delta{x}) $$ Does it matter if S' is moving away to the right, or to the left, of S? I logically think not, because why would that matter? Surely that wouldn't change the value of ## \Delta{t'} ##. But then if you switch S' and S, S' being stationary and S moving away from S', you get a different equation: $$ \Delta{t}=\gamma(\Delta{t'}+\frac{v}{c^2}\Delta{x'}) $$
