Find Number of Weeks

Joe and Steve are saving money. Joe starts with $105 and saves $5 per week. Steve starts with $5 and saves $15 per week. After how many weeks do they have the same amount of money?

I think two equations are needed.

Let w = number of weeks

Joe's equation: y = 105 + 5w

Steve equation: y = 5 + 15w

Is this OK so far?

Brother, if I ask for a hint or ask if my steps are OK so far, don't solve the problem unless I ask you to do so.
