Tom is 15 and his father is 35 . Nice question, I liked it.
Five Years Ago, Tom Was One Third As Old As His Father Was Then. In 5 Years, Tom Will Be Half As Old As His Father Will Be Then. What Are Their Ages Now?
Set: Tom is x years old now, then his father is 3(x-5)+5 years old.
X+5=1/2(3x-15+5+5)
2x+10=3x-5
x=15, 3x=45
X+5=1/2(3x-15+5+5)
2x+10=3x-5
x=15, 3x=45
