Question 1132219
Jamie is 5 years older than her brother. Five years ago she was 2 times older than her brother. How old are they?
-----------
Five years ago she was 2 times older than her brother.
1 time older = 2 times as old.
2 times older = 3 times as old.
---
The difference is always 5 years.
----
5 years ago:
J = B + 5
J = 3B
----
Sub for J in the 1st eqn
3B = B + 5
2B = 5
B = 2.5
J = 7.5
-----------------
Add 5
===============
B = 7.5
J = 12.5
=====================================
"2 times older" shows the author of the problem should find other work.
But, at least it's not "2 times younger."
