system%28t=4%2Ct=a%2F2-6%29


a%2F2=t%2B6
a=2t%2B12
a=2%2A4%2B12
a=20

Even a second or third grade young student can solve this problem MENTALLY, without using equation/equations

and even without knowing what an equation is and how to solve it.

and hence, the total Amy's age is  10+10 = 20 years.    ANSWER
