Question 993834
The usage is not right.  Irregardless,...


p,m,j, their ages now.
Unclear the order of their ages.
Let n be any positive integer.
Assuming {{{system(p=2n+1,m=2n+3,j=2n+5)}}}.


{{{p+m=j-5}}} for <i>The sum of the ages of Peter and Margaret equals Jack’s age before 5 years.</i>


{{{(2n+1)+(2n+3)=(2n+5)-5}}}
Use this equation to solve for n, and then evaluate p, m, and j.
If this does not work, then the question description is badly formed.
