Question 381741
 brian is 26 years older than his daughter kim. the sum of their ages is twice the difference of their ages. find their ages.
-----
Equations:
b = k+26
b + k = 2(b-k)
-------------------------
Substitute for "b" and solve for "k":
k+26 +k = 2(k+26-k)
---
2k + 26 = 52
2k = 26
k = 13 (Kim's age)
-----------------------
Since b = k+26, b = 39 yrs (brian's age)
