toby is 4 years younger than debby . thrice the sum of the ages of toby and debby equals their mother ’ s age . if the age of the mother is 60 , find the ages of toby and debby ?
let the age of debby be x and toby be x - 4 3 ( x + x - 4 ) = 60 x = 12 the ages of toby and debby are 8 and 12 . answer : a
add(multiply(divide(subtract(divide(60, const_3), 4), const_2), const_100), subtract(divide(60, const_3), divide(subtract(divide(60, const_3), 4), const_2)))
