<font face="Times New Roman" size="+2">


Let *[tex \LARGE x] represent the "number of years ago".  The older guy is *[tex \LARGE 50\ -\ x] at that time, and the younger is *[tex \LARGE 30\ -\ x] at that time and we know that:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 50\ -\ x\ =\ 2(30\ -\ x)]


Solve for *[tex \LARGE x]
