\begin{gathered} (x)/(5)-(5+x)/(20)=(7)/(16) \\ (x(20)-5(5+x))/((5)(20))=(7)/(16) \\ (20x-25-5x)/(100)=(7)/(16) \\ (15x-25)/(100)=(7)/(16) \\ 15x-25=(100)((7)/(16)) \\ 15x-25=(700)/(16) \\ 15x=(700)/(16)+25 \\ 15x=(275)/(4) \\ x=(275)/(4(15)) \\ x=(275)/(60)=(55)/(12) \\ \text{The value of x is }(55)/(12) \end{gathered}
