Question 584074
Pat is 32 years older than his son Patrick. In 4 years, the sum of their ages will be 90. How old are they now? 
--------
Equations:
p = s + 32
p+4 + s + 4 = 90
-----
Substitute for "p" and solve for "s":
s+32 + 4 + s + 4 = 90
---
2s + 40 = 90
2s = 50
s = 25 yrs (Son's age)
---------------------
father's age = 25+32 = 57
