every system of linear equations. The fact that such a procedure exists makes systems of linear equations very unusual. If you pick a system of equations at random (i.e. not from a course or textbook) the odds are that you won’t be able to solve it. Fortunately, it is possible to use linear systems to approximate many real world situations. SYSTEMS OF LINEAR EQUATIONS 1.1.

If you pick a system of equations at random (i.e. not from a course or textbook) the odds are that you won’t be able to solve it. Fortunately, it is possible to use linear systems to approximate many real world situations. Our quest is to find the “best description” of the solution set. In system (3), we don’t have to do any work to determine what the point is, the system (because technically it is a system of linear equations) is just each coordinate listed in order. If the solution set is a single point, this is the ideal description we’re after.
