You can put this solution on YOUR website!
I will not here go through all the steps, but if you follow the description literally, then you form:
system%28r=2g%2Cg-4=2%28d-4%29%2Cr%2B10=2%28d%2B10%29%29

You can work that up to system%28r=2g%2Cr-g=14%29;
and you can solve for the value of r.

Reid is 28.
