The first equation (  3  x  +  3  =  p) is correct, but you lost your focus on the second equation. So now Peter&#039;s age is   p and his sons age is   x. After three years, Peter&#039;s age will be   p  +  3 and his son&#039;s   x  +  3. So &quot;After three years, Peter&#039;s age (  p  +  3) will be ten years more than twice his son&#039;s age&quot; becomes  (  p  +  3  )  =  10  +  2  (  x  +  3  )
