Problema Solution
The mother is 6 years more than three times older than her son. Four years ago, she was five times older as her son. How old is her son now ?
Answer provided by our tutors
let 'x' represent the age of the son, then '3x+6' represents the age of the mother
Four years ago, she was five times older as her son:
5(x-4) = (3x+6-4)
solving for 'x' we have x=11
her son is now 11 years old
