Step-by-step explanation:

Five years ago I was thrice as old as my son and ten years later I shall be twice as old as my son. How old are we now?

let x=son's age now

5 yrs ago:

x-5=son's age

3(x-5)=parent's age

10 yrs later:

x+10=son's age

2(x+10)=parent's age

parent's age 10 yrs later=parent's age 5 yrs ago plus 15

2(x+10)=15+3(x-5)

2x+20=15+3x-15

x=20

3(x-5)+5=50

son's age now: 20

parent's age now: 50
