I can't find any similar examples of these proportion problems.... I've found the same principle but much simpler so it doesn't help. I would totally appreciate it if one of you could walk me through one of these problems. My Geometry book doesn't even have any examples. Thanks!
x/x-3 = x+4/x
x+1/6 = x-1/x
Sorry if these are dumb. I just have no idea how to do it.
