Hi,
Just realised that I posted at the wrong level...no wonder nobody answers.....
I am stumbled by this Maths question below:
Simeon and Alvin had 116 marbles at first.
After Simeon bought another 8 marbles and Alvin gave away 20 of his marbles to his sister,
they both had the same number of marbles left. How many marbles did Alvin have at first?
I hope someone can explain how to get the answer.
Thank you for your help

Solution:
Total now  116+820= 104
Each now  104/2= 52
Alvin at first  52+20 =72
Ans: 72 marbles
