Calculating Distance Traveled for Two Skaters

[IDKPhysics101]

Two skaters of mass 9.2 kg and mass 3.0 kg stand 8.7 m apart, each holding the end of a rope stretched between them. If each skater pulls himself along the rope until they both meet how far (in m) has the person with the mass of 9.2 kg travel before stopping. Assume that friction is negligible. (Hint: make the 9.2 kg skater your zero reference point and find the center of mass)

X=2.13m?

I don't have time to type my work right now. But will show work if answer is wrong to see where i went wrong.

Looks good.
