Hello, This seems like a pretty simple set of equations, but it's stumping reduce: { Subscript[V, b] == 4/3*Pi*Subscript[r, b]^3, Subscript[V, a] == 4/3*Pi*Subscript[r, a]^3, V == Subscript[V, b] - Subscript[V, a], \[Rho] == m/V }; % /. {Subscript[r, b] -> 5.75, Subscript[r, a] -> 5.70, \[Rho] -> 8.92}; Reduce[%] Of course, Solve can handle it. (Change the last expression to Solve[%,m].) Any thoughts on helping Reduce out here? Ed
