Is the intersection of the sets of solutions of the individual equations.įor example if these equations define lines on the plane, the intersection Whole plane (if a= b= c=0), or empty (if a= b=0 but c is not 0). This set of points is either a line (if a or b is not 0) or the The geometric meaning of systems of linear equationsĬonsider an ( x,y)-plane and the set of points satisfying ax+by=c. Is the general solution of the original system. Since this system is equivalent to the original system, we get that x=5, y=2 Now we can use the third operation and multiply the second equation by 1/2:įinally we can replace the first equation by the sum of the first equation and
SOLUTION OF LINEAR EQUATION SYSTEMS WITH MATRIX OPERATIONS PLUS
We can first replace the second equation by the second equation plus the System, meaning that they have the same solutions. Multiply an equation by a non-zero number.Īfter each of these operations is equivalent to the original.Replace an equation by the sum of this equation and another equation multiplied by a number.Operations that one can apply to any system of linear equations: It is not possible to reduce every system of linear equations to this form, but Where every equation has only one unknown and all these unknowns are different. The simplest system of linear equations is In order to find a general solution of a system of equations, one needs to simplify it as much as possible. This is a general solution of our system. This system has infinitely many solutions given by this formula: This system has just one solution: x=5, y=2. Is any common solution of these equations.Īll solutions for different values of parameters. The solution has two parameters t 1 and t 2 Īny sequence of linear equations. This command asks Maple to solve the system of equations. This command starts the linear algebra package. There may be many formulas giving all solutions of a given equation. Thus this is a (the) general solution of our equation. These formulas give all solutions of our equation meaning that for everyĬhoice of values of t and s we get a solution and every solution is obtained We can set arbitrary values of x and y and then solve (2) for z. X 1.,x n which make (1) a true equality.Ī linear equation can have infinitely many solutions, exactlyĮquation (2) has infinitely many solutions. This equation has three unknowns and four coefficients (3, -4, 5, 6).Ī solution of a linear equation (1) is a sequence of numbers Where x 1.,x n are unknowns, a 1.,a n,b are coefficients.
