[R] solving system of equations involving non-linearities

Many thanks, BBsolve works like a charm. 

First I thought I should use the squares of the equations because BBsolve
would use some minimization objective function anyway but it actually only
works if I don't use the squared equations. I'll check the documentation if
I find something about the objective.

Thanks for the help,
