Max is 23 years younger than his father.Together their ages add up to 81.

Let Max's age be m, and his fathers' age be f. We're given:

1. m = f - 23 <-- younger means less
2. m + f = 81

Substitute Equation (1) into (2):
(f - 23) + f = 81

Combine like terms to form the equation below:
2f - 23 = 81

Typing this equation into our search engine, we get:
f = 52

Substitute this into Equation (1):
m = 52 - 23
m = 29
