Answer:
3/11 I think you divide both by 2.
Let Peters age be x
Phil's age is 1/5x+7---------------------------(i)
Phil's age can also be calculated as
4(1/5x+7)=2x-2--------------------------------(ii)
So,
4/5x+28=2x-2
28+2=2x-4/5x
30=10/5x-4/5x
30=6/5x
x=30*
![\frac{5}{6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B5%7D%7B6%7D%20)
x=25
75/25= 3
72/24= 3
7*3= 21
x= 21
I hope this helps!
