Eight years back, a father was 52 years older than his son. At present the father is 5 times as old as the son. How old will the son be three years from now?  Choose the correct choice:
A) 10 years  B) 12 years  C) 14 years  D) 16 years  E) 18 years
Using linear equations to convert the word problem:   ** F = fathers current ageS = sons current age   #1 Eight years back, a father was 52 years older than his son: F-8 = 52 + (S - 8)   #2 At present the father is 5 times as old as the son: F = 5*S   How old will the son be three years from now?: S + 3 = ?   With two variables and two linear equations we are able to solve the problem:   (S*5) - 8 = 52 +S -8   4S=52   S = 13   S + 3 = 13+ 3=
