Sam is four years younger than Jason. In four years, Jason will be twice as old as Sam is now. How old is Sam?

Answer 1

You can rewrite the sentences as algebraic equations:

Sam is four years younger than Jason.
S = J - 4

In four years, Jason will be twice as old as Sam is now.
(J + 4) = S * 2

So your two equations are:
S = J - 4
(J + 4) = S * 2

Now, use algebra to solve for S.

I hope this makes sense. If you need any further help, please feel free to reply to this thread.

Answer 2

Thanks for your help but also how do u find the answer by using algebra

Answer 3

You need to solve this system of equations:

S = J - 4
(J + 4) = S * 2

Do you have any thoughts on how to do this?
