Let B = Benjamin and J = Jeremiah
So B = J + 8 ---------------- Now
and B + 5 = 2(J + 5) ------- In Five years
Therefore and substituting for one in terms of other --> B + 5 = 2(B - 8 + 5) or B = 11
Answers is B = 11 and J = 3
So B = J + 8 ---------------- Now
and B + 5 = 2(J + 5) ------- In Five years
Therefore and substituting for one in terms of other --> B + 5 = 2(B - 8 + 5) or B = 11
Answers is B = 11 and J = 3
