Let’s break it down! If we say Jake’s age is J and his brother’s age is B, we know two things from your question: J + B = 30 and J = 2B. If we substitute the second equation into the first, we get 2B + B = 30. This simplifies to 3B = 30, so B (the brother’s age) is 10 years old. That makes Jake 2B, or 20 years old! So, Jake is 20 years old, and his brother is 10 years old. Easy as pie!
