Question: New to Maple Having Trouble

So as the title claims I am new to maple and am having trouble with trying to learn how exactly to accomplish certain things.

Mainly being that I am having trouble with a set of exquations that are equal to zero which I then set equal to eachother in order to solve for the values of the variables (x,y)

for example lets say that

f1:= x3-x2-(y2-y)x = 0

f2:= -1-ln(y)+ln(x-y) = 0 

now from here I start to become a bit iffy on what exactly I am supposed to be doing. I have a line of code stating 

f3:=f1=f2

and from there I have had absolutely no luck what so ever. 

any help would be much appreciated.
