You can put this solution on YOUR website! Alan is 7 years older than Nicole. In 5 years the sum of their ages will be 49. How old is Alan now?
-------
Equations:
a = n + 7
a+5 + n + 5 = 49
-----------
Substitute for "a" and solve for "n"::
n + 12 + n + 5 = 49
2n + 17 = 49
2n = 32
n = 16
-----
a = n+7 = 16+7 = 23
