Tony is 4 years older than Heather, and Heather is 5 years old younger than Larry. If the sum of their ages is 69, how old is Tony?
This is a math problem, and major part of this solution is just translating the sentence form of this problem into equation form. Here's how I would do it.
"Tony is 4 years older than Heather" --> H + 4 = T
"Heather is 5 yrs younger than Larry" --> H + 5 = L
"Sum of their ages is 69" --> H + T + L = 69
So now you have 3 equations and 3 unknowns, which means you can solve the equation by substitution.
H + (H+4) + (H+5) = 69
3H + 9 = 69
3H = 60
H = 20. Therefore, T = 24 and L = 25
So, Heather is 20, Tony is 24 and Larry is 25.
What else can I help you with?
