The two numbers are 31 and 35.

Step-by-step explanation:

Let,

one number = x

2nd number = y

According to statement;

x+y=66 Eqn 1

y=x+4 Eqn 2

Putting y=x+4 from Eqn 2 in Eqn 1;

$x+(x+4)=66\\x+x+4=66\\2x=66-4\\2x=62\\Dividing\ both\ sides\ by\ 2\\\frac{2x}{2}=\frac{62}{2}\\x=31\\Putting\ x=31\ in\ Eqn\ 2\\y=31+4\\y=35$

The two numbers are 31 and 35.
