A person is 5 years older than twice their sibling's age. If the person is currently 27 years old, how old is the sibling?
11 years
Let the sibling's age be \(x\) years.
The person is 5 years older than twice the sibling's age, so the person's age \(= 2x + 5\).
Given the person is 27 years old: \(2x + 5 = 27\).
\(2x = 22 \Rightarrow x = 11\).
Hence, the sibling is 11 years old.
