Ask HN: Need help solving simultaneous nonlinear equations

I am trying to solve these following equations for x and y in terms of constants a, b, Q, c and C (1) exp(a)(x+y+Q)^b + exp(a)bx(x+y+Q)^(b-1) – c = 0 (2) exp(a)(x+y+Q)^b + exp(a)by(x+y+Q)^(b-1) – C = 0 I've attempted several approaches, also using iterative methods, but have not found a solution. Any help would be greatly appreciated!
