Can you answer this Bill and Joe have 60 dollars between them. Bill has half as much as Joe. How much does Bill have

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.
