The youngest brother's age is 21 years.

Step-by-step explanation:

Given:

The ages of 3 brothers are consecutive integers.

If the oldest brothers age is decreased by twice the youngest brother age the result is -19

To find the age of the youngest brother.

Solution:

Let the age of youngest broth be =  years

The ages are consecutive integers.

So, age of the next older brother will be = years

The age of the oldest brother will be = years

The oldest brothers age is decreased by twice the youngest brother age.

The above statement can be represented as:

⇒

Simplifying.

⇒

⇒

Subtracting both sides by 2.

Multiplying both sides by -1.

∴

Thus, the youngest brother's age is 21 years
