Recently, I've been trying to implement some working version of the Glicko Rating System for fun.

However, I fail to understand how to programmatically isolate R in Step 2. As you can see R appears on both sides of the equation and for a variable number of instances. How would I programatically solve for R using python?

Thanks for any help :)

EDIT: Actually shouldn't the R in step 2 be R_0 on the right hand side of the equation? Is this a typo? Note in "The Glicko system" by Professor Mark E. Glickman, the equations are identical except for all Rs being on one side and R' being on the other.
