Answer :
Two groups (larger group A and smaller group B) can use any variables instead of a and b.
A + B = 20 (because you have a total of twenty objects)
2A = 3B
In group A there is a total of 12 objects and in B there is a total of 8 objects
A + B = 20 (because you have a total of twenty objects)
2A = 3B
In group A there is a total of 12 objects and in B there is a total of 8 objects
