Derive that (x + y/4)/Φ is the oxidizer coefficient a in the combustion reaction

where Φ is the air–fuel equivalence ratio. Start by considering the case where Φ = 1; i.e., by doing C, H, O, and N balances you get a = x + y/4 when the mixture is in stoichiometric proportions. Then show how Φ enters in when the mixture is not stoichiometric.
