Zinc (Zn) does not have variable valency
Cu 2 +
iron is in the III oxidation state
Iron nitrate and copper. Fe + Cu(NO3)2 -> Fe(NO3)2 + Cu
All are metals.
Fe + CuSO4 ------> FeSO4 + Cu This equation is balanced. The displacement here happens when the iron knocks copper out of the compound and replaces it. The copper then forms around the iron giving it a brassy colouring.
Variable valencies are the valencies which can change e.g. Fe (iron) can either have the valency of 2 (Fe II) or 3 (Fe III)

Certain elements combine with other atoms, donating, accepting or sharing electrons in different proportions depending on the nature of the reaction. For example, iron combines with oxygen to form ferrous oxide as well as ferric oxide. In the formation of ferrous oxide, iron exhibits a valency of +2, whereas in ferric oxide, it has a valency of +3. This is termed variable valency
Fe + Cu(NO3)2 --> Fe(No3)2 + Cu

copper (Cu)
Cu 2 +

2 Fe + 3 CuO -> Fe2O3 + 3 Cu
iron is in the III oxidation state
Iron nitrate and copper. Fe + Cu(NO3)2 -> Fe(NO3)2 + Cu
looks like a single displacement reaction. Cu + AgSO4 Thank you very much!
