How does one assign from a solution set? In the following example, I would like to get the square roots of b and c where when solved, b=9 and c=10. How does one assigned the values obtained in the solution to be able to manipulate them later? Thanks. > `πx`^2 = `kπ`(y^2-x^2); print(`πx`^2 = `kπ`(y^2-x^2)); 2 / 2 2\ πx = kπ\y - x / > `kπ`(y^2-x^2) = Pi(z^2-y^2); print(`kπ`(y^2-x^2) = Pi(z^2-y^2)); / 2 2\ / 2 2\ kπ\y - x / = Pi\z - y / > `πx`^2 = `kπ`(z^2-y^2);
