Hello All, If I solve a set of simultaneous equations and get a simple answer like zrule = z-> x^2 + y^2 but I then want to evaluate fn[x_,y_] := z + some more stuff..... I tried saying fn[x_,y_] := Replace[z,zrule] + .... but it doesn't seem to handle it the way I wanted... Is there a correct way of doing this ? thanks John B
