<h3>Answer :- </h3>
<h3>Solution :- </h3>
- Let the age of victor be X .
- and, the age of Mr.Smith be = 81 + x
♧ <em>So, after 3 years = x+81 +3</em>
- 81 + 3 + x = 4 ( x + 3 )
- 84 + x = 4x + 12
♧ <em>now grouping the variables and constants together we get,</em>
- 4x-x=84-12
- 3x = 72
- x = 72/3
- x = 24
♧ <em>Thus, Victor's present age is 24 yrs.</em>

Answer:
First equate 3x + 7 to any unknown
3x + 7 = P
Then make x the subject of the formula
3x + 7 = P
3x + 7-7= P-7
3x = P-7
3x ÷ 3 = (P-7) ÷ 3
x = (P-7) ÷3
Then interchange x with the unknown which I have as P
x = (P-7) ÷ 3
P = (x-7) ÷ 3
Then inverse of f(x)
is;
f-1(x) = (x-7) ÷ 3
