Hi, need help with this Systems of Linear Equations: Solving by the Addition Method, the problem is..

Jan has 2,000$ more invested in a stock that pays 9% interest, than in a savings account paying 8%.. If her total interest for 1 year is $860, how much does she have invested at each rate?

I know that I'm really late to this, but I think I would have to know how the $2000 is distributed first.
