Let R and S be two 2D coordinate systems.
I know the coordinate of 3 non-aligned points A,B,C in both systems.
How can I find the coordinate of O,P (or any other point from S) in R?
Sorry for the poor wording, I'm not familiar with mathematical stuff.
Thanks!

If you don't give some definite relation between the points I'm afraid the question cannot be solved...

What kind of relation is required? A,B,C are arbitrary points. I just know theirs coordinates. From the above picture: B could be (2.5, 3.3) in base S and (2.2, 2.3) in base R. Is A,B and C enough to compute point O? (0,0) in S and (Xr,Xy) in R
