I can put something under the back of the bed, which raises the back, but the front still is too high. What do I do?

(QUICK EDIT!!!: I bought this printer for ~$50, they were selling it because it wouldn't print. I fixed that issue (hotend fan wouldn't work and heat creep was present, so i bought and installed a working fan), but now when it prints, the prints are coming out with the layers on the bed showing an obvious bed leveling problem. The printer was apparently modded once or a few times (I noticed a unicorn nozzle but I don't know what else was modded).
