The examiner wishes to test your knowledge on balancing of chemical equation.
To balance, calculate the total number of H atom on the RHS, and balance with one on the LHS, you'll discover it's 8. That would be the value of P.
Next will be the number of moles of NO on the RHS, you'll discover it is 2.
Thus, P = 8 while X = 2 .
