[R] Solving Systems of Non-linear equations

I am trying to write a function that will solve a simple system of nonlinear equations for the parameters that describe the beta distribution (a,b) given the mean and variance.

mean = a/(a+b)
variance = (a*b)/(((a+b)^2) * (a+b+1))

Any help as to where to start would be welcome.
