Question 6199: Adam is half as old as Bob and three times as old as Cindy. If the sum of their ages is 40, what is Bob's age?
I know that the answer is 24 through a technique called "Backsolving". But I would like to know how to translate the problem into an equation or equations that can be used to solve the problem.
I got only this far:
Let x=Bob
Let y=Adam
Let z=Cindy
x+y+z=40
But after this I am confused about how to translate the the y and z variables into an equation format to get the correct solution.
