Answer:

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 = x  years

The ages are consecutive integers.

So, age of the next older brother will be = (x+1) years

The age of the oldest brother will be = (x+2) years

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

The above statement can be represented as:

⇒ (x+2)-2x

Simplifying.

⇒ x-2x+2

⇒-x+2

The result for the above expression = -19.

So, we have:

-x+2=-19

Subtracting both sides by 2.

-x+2-2=-19-2

-x=-21

Multiplying both sides by -1.

∴ x=21

Thus, the youngest brother's age is 21 years
