Question

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

Answer 1

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.
