Loosen the rear axle nut. Slide the wheel back. Tighten the nut. Job done.
That is the simple answer.
For a more complete answer you need to refer to a manual or find someone familiar with that specific model and year. Most bikes have some sort of mechanism on the rear axle or swing arm that makes the adjusting and making sure that both sides are the same distance back fairly easy.
I believe that a 1988 YZ-125 has a small bolt on a bracket which is held to the swing arm by the axle. This bold sets the distance for the wheel. Set the bike on a stand. Loosen the large axle nut (just loose, do not remove). Loosen the lock nuts on the adjusting bolts, each side. Push on the wheel so that you are pushing against the adjusting bolt. Adjust for proper chain tension (Note, proper chain slack is essential, the chain needs to be able to "droop" 1"-1/2 or so). Make sure your wheel is straight, then tighten the axle nut, then tighten the lock nuts on the adjusting bolts.
