Question 832591
Let the son's age be s, therefore the
Function of the Man's age = 5s - 3
thus (5s-3)+s = 37

simplifies to 6s - 3 = 37, 6s = 40; thus the sons age s = (40/6)

therefore the fathers age is 5(40/6) - 3 = (91/3) years

remember to leave your answer in fractions to maintain precision otherwise, if if you round off you will get rounding errors that lead to the wrong answer.

to confirm,

(91/3)+(40/6) = (222/6) exactly = 37 years
