Answer:
Step-by-step explanation:
If Anna's age is represented by A, then 12 more than Anna's age will be ...
   12 + A
Jason's age is said to be 12 more than Anna's age, so ...
   J = 12 + A
__
The sum of their ages will be J + A. That is said to be 50, so ...
   J + A = 50
_____
These equations can be solved by using the first to substitute for J in the second.
   (12 +A) +A = 50
   2A = 38 . . . . . . . . subtract 12
   A = 19 . . . . . . . . . . divide by 2
   J = 12 +19 = 31 . . . find Jason's age
Jason is 31; Anna is 19.
