Question 995696: Q:A father is now four times as old as his son. Five years ago, he was seven times as old as his son. How old are they now?
I got up to letting the son's age be "x" years old and his father's age being "4x" years old. But everything I tried from there gave me wrong answers.

            NOW       FIVE YEARS AGO
FATHER      4x         4x-5
SON          x          x-5

The description's second sentence means 4x-5=7%28x-5%29.
