How do we know which balanced equations to use for the reaction given? Where do the equations from the solutions manual come from?

Hi, this is just an example of Hess' Law where we add the reactions together to get the final overall balanced overall reaction and the overall reaction enthalpy. I do not think we will be expected to know the balanced equations of formations of compounds without any information given to us on the final.
