Question 4207: Father's age is three years more than three times the son's age. After three years, father's age will be ten years more than twice the son's age. What is the father's present age. Answer by rapaljer(4671) (Show Source):
x+3 = son's age in 3 years
3x+3 + 3 = father's age in 3 years
"Father's age will be ten more than twice the son's age"
3x+3 + 3 = 2 (x+3) + 10
3x + 6 = 2x + 6 + 10
x = 10 = son's age now
3x+3 = 33 = father's age now
Check: In 3 years, the son will be 13 and the father will be 36, which is indeed 10 more than twice the son's age.
