Extremely useful for solving systems of equations. History here but I suppose you googled that too ?

Actually, determinants rarely used anymore for solving general linear systems of equations, because there are so many more efficient and simpler methods available. However, for specially-structured systems, determinants can, indeed, be the best way of solving them. They are also very useful theoretically.
