The legal age to cast a vote in Singapore is \(21\) years old and above. Aliff is \(5\) years younger than twice of Jane's age. The sum of their age is at most \(43\). Jane claims she can vote in four years' time. By letting \(x\) years old be Jane's current age, form an inequality and justify if Jane is correct.[4]
