J - R = 5  now.   ("jamee is 5 years older than rachell")

In 15 years, Jamee will be (J+15) years old, while Rachel will be (R+15).


So, you have these two equations

J - R = 5,                (1)
(J+15) + (R+15) = 45.     (2)


Simplify eq(2). You will have

J - R =  5,               (1')
J + R = 15.               (2')


Add equations (1') and (2')  (both sides). You will get

2J = 5 + 15 = 20  ====>  j =  = 10.


Thus Jamee is 10 years now.


Then Rachel is 10-5 = 5 years old.

Solved.
