Use a convenient variable, such as "x", for her age. Then, 3 years ago her age was x-3, in three years, her age will be x+3. Write an equation with this data:x = 3(x+3) - 3(x-3)And solve it:x = 3x + 9 - 3x + 9x = 18Use a convenient variable, such as "x", for her age.

How can 2 fathers and 2 sons divide three cars among themselves with each one getting one?
This is a riddle where the answer revolves around the status of being a father or a son. There are only 3 cars, and each person gets one, so there can only be 3 people. Thus one of the fathers must also be one of the sons. This can be achieved by having the 3 people as grandfather, father, and son. That means there are two sons, and two fathers, but only 3 people.

A father is thirty years older than his son when one fifth of the fathers age is added to one third of the son age the result is fourteen find the son age?
f = s + 30, f/5 + s/3 = 14 or 3f + 5s = 210 3 x (s + 30) + 5s = 210 ie 3s + 90 +5s = 210 ie 8s = 120 so s = 15 Check: Father 45, son 15, 45/5 = 9, 15/3 = 5, 9 + 5 = 14 QED
