The simple rules of algebra suffice.
As long as R ~= -1 and Y ~= 1, we can solve for R in terms of Y. I suppose the symbolic toolbox would do it if you are that algebraically challenged. I don't wish to do your homework for you, but I would start by multiplying by (1+R), thus the issue with R == -1.
Solve for R. Note that in your example as posed with real Y, the solution will always be real IF one exists. Here I get R = -7/5.
R = -7/5;
