Let f and s be present ages of father and son
f + s = 55. **eqn i
After f-s years, the son's age will equal the present age of father. Given that after f-s years, the sum if their ages will be 93.
(s+(f-s)) + (f+(f-s)) = 93
f + 2f - s = 93
3f - s = 93. **eqn ii
Adding eqns i and ii:
4f =148
f = 148/4
= 37
substituting in eqn i:
37 + s = 55
s = 55 - 37
= 18
Father is 37 years old
son is 18 years old
f + s = 55. **eqn i
