Suppose event 1 occurs at time t. Then event 2 occurs at time t+4
So the two events are (t,3) and (t+4,9)
Now find the t-coords of the events in the moving frame. (You already know how to find the events in the moving frame.)
Yes I used t=1 and t=5 and i got the x component to be the same, but the x component is space isn't it? In order for an event to be simultaneous doesn't the time component need to be the same?

I think that you're swapping the x and t coords somewhere. Put up your working.
