--------
In 3 years, he's 2x her age and 20 years older.
--> 20 & 40 in 3 years.
--> 17 & 37 now.
No setup or equation needed.

m, Meg
p, Phillip

The description turned into equations:
system%28m=p-20%2Cp%2B3=2%28m%2B3%29%29


p%2B3=2%28%28p-20%29%2B3%29
p%2B3=2%28p-17%29
p%2B3=2p-34
3%2B34=p
highlight%28p=37%29


m=p-20
m=37-20
highlight%28m=17%29
