Q. Wyatt is the oldest of three siblings whose ages are consecutive integers. If the sum of their ages is 39 , find Wyatt's age.Answer:
Denote Wyatt's Age: Let's denote Wyatt's age as W. Since the siblings have consecutive ages, the other two siblings would be W−1 and W−2 years old. The sum of their ages is given as 39. We can write this as an equation:W+(W−1)+(W−2)=39
Simplify Equation: Now, let's simplify the equation by combining like terms: 3W−3=39
Isolate Term with W: Next, we add 3 to both sides of the equation to isolate the term with W: 3W−3+3=39+33W=42
Solve for W: Now, we divide both sides of the equation by 3 to solve for W:33W=342W=14
Check Solution: Wyatt's age, W, is 14. To check if this is correct, we can add the ages of all three siblings:Wyatt's age: 14Second sibling's age: 14−1=13Third sibling's age: 14−2=12Sum of ages: 14+13+12=39The sum matches the given total age of 39, so our solution is correct.
