Hence, the smaller number is:

8

Let the number be x.

This means that twice the number is represented as: 2x

Now three more than twice the number x is represented by: 2x+3

It is given that:

The sum of a number and three more than twice that number is 27 .

This means that:

$x+2x+3=27\\\\\\i.e.\\\\\\3x+3=27$

Now on subtracting both side by 3 we get:

$3x=27-3\\\\\\i.e.\\\\\\3x=24$

on dividing both side by 3 we get the value of x as:

x=8

The smaller number is: 8
