Answer:

  Sam is 24; his mom is 48.

Step-by-step explanation:

We can let x and y represent Sam's age and his mom's age, respectively.

  y = 2x . . . . . Mom is twice Sam's age

  y -12 = x + 12 . . . . Mom's age 12 years ago is the same as Sam's age 12 years from now

__

Substituting for y in the second equation, we have ...

  2x -12 = x + 12

  x = 24 . . . . . . . . . add 12-x to both sides

  y = 2(24) = 48

Sam is 24; his mom is 48.
