Like if you say:

2*x + 1 = x

Now if you rearrange then you'll get:

2*x - x + 1 = 0   =>   x + 1 = 0   =>   x = -1


So he probably meant that you should
solve this equation with respect to x:

(r1 + (R - x)/R/r1)*sin(atan(x/p(x))) - x = 0


Unfortunately; I suspect that it is rather non-
trivial to find analytical solutions for it
(especially with higher degrees of your polynome).
