Full solution

Q. Wyatt is the oldest of three siblings whose ages are consecutive integers. If the sum of their ages is 3939 , find Wyatt's age.\newlineAnswer:
  1. Denote Wyatt's Age: Let's denote Wyatt's age as WW. Since the siblings have consecutive ages, the other two siblings would be W1W - 1 and W2W - 2 years old. The sum of their ages is given as 3939. We can write this as an equation:\newlineW+(W1)+(W2)=39W + (W - 1) + (W - 2) = 39
  2. Simplify Equation: Now, let's simplify the equation by combining like terms: 3W3=393W - 3 = 39
  3. Isolate Term with W: Next, we add 33 to both sides of the equation to isolate the term with WW: \newline3W3+3=39+33W - 3 + 3 = 39 + 3\newline3W=423W = 42
  4. Solve for W: Now, we divide both sides of the equation by 33 to solve for W:\newline3W3=423\frac{3W}{3} = \frac{42}{3}\newlineW=14W = 14
  5. Check Solution: Wyatt's age, WW, is 1414. To check if this is correct, we can add the ages of all three siblings:\newlineWyatt's age: 1414\newlineSecond sibling's age: 141=1314 - 1 = 13\newlineThird sibling's age: 142=1214 - 2 = 12\newlineSum of ages: 14+13+12=3914 + 13 + 12 = 39\newlineThe sum matches the given total age of 3939, so our solution is correct.
