So look at  your NO2 column -- where you have MEASURED values of NO2 at 
room temperature and the high or low temperature.   In the case of the 
high temperature ice table the change in NO2 was +2x


initial + 2x = equilbrium


(equilibrium - initial)/2 = x


then for the N2O4 column it will be


initial - x = equilibrium


So you use the value of x you determined in the NO2 column to figure out 
the equlibrium value in the N2O4 column.
