Question 1121275
<font face="Times New Roman" size="+2">


Let *[tex \Large x] represent the man's age and *[tex \Large y] represent the son's age.


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  x\ =\ 3y]


Five years ago then, the man would have been *[tex \Large x\ -\ 5] years old and his son would have been *[tex \Large y\ -\ 5] years old and then:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \  x\ -\ 5\ =\ 4(y\ -\ 5)]


For the second question, solve for *[tex \Large x] and *[tex \Large y] and then subtract 10 from each.
