K(Co(Co)4) in this complex , oxidation no. for cobalt is -1
here is +1 +x+4(0) =0
so x = -1
this complex is named as potassiumtetracobaltocobaltate

Dear student 
[Ti(H2O)6]3+ : H2O is a neutral ligand and the complex is positively charged hence a cationic complex. Again, x+6(0)=+3 ie,    x=-3
 
Hope this helps 
Good luck
