You have copied the question wrong.

#VO_2# is a not an ion. It is a compound formed by the following reaction and compounds have a charge of 0. It forms #VO^(+2)# when dissolved in non-oxidising acids such as #HCl#

#V_2O_5 + V_2O_3 → 4 VO_2#

So actually the equation is

#x + ((-2) + (-2)) = 0#
#x + (-4) = 0#
#x = 4#
