The main object of the linear algebra solves the line series of linear equations, solve the linear algebra series of linear equations is the foundation that resolves many actual problems, so to the linear algebra series of linear equations the further discussion of the solution is an important contents of the linear algebra. This text aim solves the general step that the general solution method and improvement of the line series of linear equations solve a method in the overview, the point elaborates solving the series of linear equations solve of keep the view method, try hard for to attain in detail with innovation. While solving the linear algebra series of linear equations a solution, the method usually use most is to broaden the series of linear equations the matrix carry on turning Chien, becoming the stairs form matrix to them, and write the line series of linear equations of the and the series of linear equations etc. price, then beg the solution of a series of linear equations according to the stairs form. This text mainly considers in beg the series of linear equations the general process for solve, adoption another a kind of more simple method: Will broaden matrix to pass directly with
