Question

I NEED HELP! PLEASE SOMEONE HELP ME OUT! tomorrow's my last day to submit my assignment.
A man is currently 4 times as old as his son. In 4 years from now he will be three times as old as his son will be then. How old is his son now?

Answer 1

Let the age of man be m, and the age of son be s.
Currently 4s=m
In 4 years 3(s+3)=(m+3)
Subtract the second equation from the first to get
s-9=-3 so s=6
m=6*4=24
Son is 9 years old now, dad is 27.

Answer 2

o.O you dont satisfy the original equation andreas

Answer 3

Oops this is wrong :)
3(s+3)=(m+3) should be
3(s+4)=(m+4)
So
s-12=-4
s=8 m=32
