Problema Solution

2 years ago, Adam was three times as old as Steve. In 4 years, Adam will be 10 years older than Steve. How old is Adam?

Answer provided by our tutors

Let

x = present age of Adam

y = present age of Steve

2 years ago, Adam was three times as old as Steve means:

x - 2 = 3(y - 2)

In 4 years, Adam will be 10 years older than Steve:

x + 4 = 10 + (y + 4)

We have the following system of equations:

x - 2 = 3(y - 2)

x + 4 = 10 + (y + 4)
