Answer:
Jason -- 36
Shauna -- 12
Explanation:
This question in set to the future 4 years so in order to actually solve it, we need to subtract the years to the present. The number of years to subtract is 8 to account for both people's combined age.
so ....
x -- shaunas age
3x + x = 56 -8
4x = 48
x= 12
Therefore Shauna is 12 years old. Because Jason is three times Shauna's age, he is 36
