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

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.

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

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?

To find Sam's age, let's set up an equation based on the information given.

Let's assume that Jason's current age is J, and Sam's current age is S.

According to the given information, Sam is four years younger than Jason, so we have the equation:
S = J - 4 (Equation 1)

In four years, Jason will be twice as old as Sam is now. So, Jason's age in four years will be J + 4, and Sam's age now is S.

The equation based on this information is:
J + 4 = 2S (Equation 2)

Now, we have a system of two equations with two variables. We can solve this system to find the values of J and S.

Let's substitute the value of S from Equation 1 into Equation 2:
J + 4 = 2(J - 4)

Expanding the equation:
J + 4 = 2J - 8

Bringing similar terms together:
J - 2J = -8 - 4
-J = -12

Multiplying both sides by -1, we get:
J = 12

Now that we have found Jason's age, we can substitute it back into Equation 1 to find Sam's age:
S = J - 4
S = 12 - 4
S = 8

Therefore, Sam is 8 years old.
