Answer:
Father's age is 63 years
Step-by-step explanation:
Let x years be the son's age.
A fathers age is three less than two times the sons age, then the father's age is
[tex]2x-3[/tex] years.
The difference in their ages is 30 years, hence
[tex](2x-3)-x=30[/tex]
Solve this equation:
[tex]2x-3-x=30\\ \\2x-x-3=30\\ \\x-3=30\\ \\x-3+3=30+3\\ \\x=33\\ \\2x-3=2\cdot 33-3=66-3=63[/tex]
Son's age is 33 years, father's age is 63 years
