Answer:
The boy's age is 8, the younger brother's age is 4.
- What we know is that the first brother has to be 8, because the equation given is x = y(younger brother) + 8
- Now we must solve the equation based off of this.
- Hmm. What would the product of twice the sum of the younger brother's age be?
- If we have already found out that the older brother's age is currently 8, we know that that 8 + 4 is 12, and in that case, the 2 must be the current age apart the brothers are, 2 years. And that would mean the younger brother is 4. Let's finish the equation.
To find the younger brother's age using the given values...
That said, everything matches up with the equation. The first brother is twice the age of his younger brother.
