One equation is simply a multiple of the other. Equivalently, the equations are linearly dependent; or the matrix of coefficients is singular.

Why a system of linear equations cannot have exactly two solutions?

A system of linear equations can only have: no solution, one solution, or infinitely many solutions.


Can a system of linear equations in two variables have infinitely solutions?

Yes.


Why could a system of linear equations have two solutions?

A system of linear equations cannot have two distinct solutions if it is consistent and defined in a Euclidean space. If two linear equations intersect at a single point, they have one solution; if they are parallel, they have no solutions. However, if the equations are dependent, meaning one equation is a multiple of the other, they represent the same line and thus have infinitely many solutions, not just two. Therefore, in standard scenarios, a system of linear equations can either have one solution, no solutions, or infinitely many solutions, but not exactly two.


How many solutions can a system of linear equations with two variables?

None, one or infinitely many.


Can a system of two linear equations have exactly two solutions explain?

No, a system of two linear equations cannot have exactly two solutions. In a two-dimensional space, two linear equations can either intersect at one point (one solution), be parallel (no solutions), or be the same line (infinitely many solutions). Therefore, it is impossible for a system of two linear equations to have exactly two solutions.


How many solutions did this linear system have?

To determine how many solutions a linear system has, we need to analyze the equations involved. A linear system can have one unique solution, infinitely many solutions, or no solution at all. This is usually assessed by examining the coefficients and constants of the equations, as well as using methods like substitution, elimination, or matrix analysis. If the equations are consistent and independent, there is one solution; if they are consistent and dependent, there are infinitely many solutions; and if they are inconsistent, there are no solutions.


Kinds of system of linear equation in two variables?

There are three kinds:the equations have a unique solutionthe equations have no solutionthe equations have infinitely many solutions.


If a system of linear of linear equations has infinitely many solutions what does this mean about the two lines?

If a system of linear equations has infinitely many solutions, it means that the two lines represented by the equations are coincident, meaning they lie on top of each other. This occurs when both equations represent the same line, indicating they have the same slope and y-intercept. As a result, any point on the line is a solution to the system.


What are the three types of system of linear equations?

What system has infinite solutions?

A system of linear equations has infinite solutions when the equations represent the same line or plane in a geometric sense. This occurs when at least one equation can be expressed as a scalar multiple or a linear combination of the others, resulting in dependent equations. In such cases, there are infinitely many points (solutions) that satisfy all equations simultaneously.


The three quantities of solution linear equations?

The three quantities of solution for linear equations are consistent, inconsistent, and dependent. A consistent system has at least one solution, either unique or infinitely many. An inconsistent system has no solutions, meaning the equations represent parallel lines that never intersect. A dependent system has infinitely many solutions, indicating that the equations represent the same line in different forms.


How do you know if a system of linear equations has one solution infinitely many solutions or no solutions?

To determine the number of solutions for a system of linear equations, you can analyze the equations graphically or algebraically. If the lines represented by the equations intersect at a single point, there is one solution. If the lines are parallel and never intersect, there are no solutions. If the lines are coincident (overlap completely), there are infinitely many solutions. Algebraically, this can be assessed using methods like substitution, elimination, or examining the rank of the coefficient matrix relative to the augmented matrix.
