Answer :
To be able to calculate the problem above, we need to set up equations. We let,
x = Bill's money
y = Joe's money
We have two unknowns so we should set up two equations. We do as follows:
x + y = 60
x = y / 2
Solving simultaneously, we will have
x = 20
y = 40
Therefore, Bill has 20 dollars.
