It is difficult to say no to a friend, but helping them cheat isn't going to help them in the long run.
Depending on how close a friend it was, I would probably offer to help them study, but if they just want you to spoon-feed them the answers, then nah. You'd be undermining your own integrity to help them undermine their own, and the result will be that they still don't understand the material, and will likely come back to you the next time they encounter a problem they can't solve.
This applies even more strongly if this is some sort of professional test/job interview.
They probably won't appreciate it if you tell them no, but if they get mad about it enough to permanently damage the friendship, that says more about them than it does about you.
For further actions, you may consider blocking this person and/or reporting abuse
