Jamie is 4 years younger than her brother. Five years from now, the sum of their ages will be 32. Find Jamie's present age.
------
Equation:
J = B-4
(J+5)+(B+5) = 32
-------------------
Substitue for "J" and solve for "B":
(B-4+5+B+5) = 32
2B + 6 = 32
2B = 26
B = 13 years (His brother's age now)
---
Since J = B-4, Jamie = 9 yrs old (Jamie's age now)
