Let Norie's age : x
then Rizza's age :x+1
Eight years ago....
Norie's age : x-8
Rizza's age :x+1-8
Sum of their ages 8 years ago
Also given that the sum of their ages was equal to Rizza's age ten years from now, which leads to
Transposing similar terms leads to....
So x=26 which is Norie's age
and Rizza's age would be 26+1=27
Ans: Norie and Rizza are 26 and 27 years old now
