Angles F and C are supplementary, then their addition is equal to 180 degrees, that is,


m\angle F+m\angle C=180

Substituting with data and solving for x:


\begin{gathered} (157-17x)+108=180 \\ (157+108)-17x=180 \\ 265-17x=180 \\ 265-17x-265=180-265 \\ -17x=-85 \\ (-17x)/(-17)=(-85)/(-17) \\ x=5 \end{gathered}
