Solve this Standard Heat of Reaction Problem

Given the standard heats of formation for the following compounds, calculate the change H2 degrees 98 for the following reaction

CH4 (g) + H2O (g) >>>>>> CH3OH (l) + H2 (g)


Change in H Degree F (kj/mole)  -75       -242          -238       0


I need to see how to solve this, and most importantly, the answer
