Scott is 4 times older than Bethany. In six years from now, Scott will only be 3 times older than Bethany. Write down two equations to describe the relationship between their ages. Now solve the equations to find out old each of them is. Show working

For this item, we let x and y be Scott's and Bethany's ages, respectively. For their current ages,

x = 4y

In six years,

x + 6 = 3 (y + 6)

The values of x and y in this item are 12. Therefore, Scott's and Bethany's ages are 48 and 15 years old, respectively.
