Question 714572
<font face="Times New Roman" size="+2">


*[tex \LARGE p_1] years ago, Baxter was *[tex \LARGE f_1] as old as his father was then.  In *[tex \LARGE p_2] years Baxter would be *[tex \LARGE f_2] as old as his father will be then.  Find their ages now.  Note:  Unless you have the absurd situation where Baxter is older than his father, *[tex \LARGE f_1] and *[tex \LARGE f_2] will be fractions.


Let *[tex \LARGE x] represent Baxter's age now.  Let *[tex \LARGE y] represent his father's age now, then:


*[tex \LARGE x\ -\ p_1\ =\ f_1(y\ -\ p_1)]


and


*[tex \LARGE x\ +\ p_2\ =\ f_2(y\ +\ p_2)]


Solve the system for *[tex \LARGE x] and *[tex \LARGE y] once you are given the other parameters.
