How do you know if a linear system is consistent or inconsistent?

Two curves are consistent if it is possible for some point to be on both. (Being on one curve is consistent with being on the other.) There is an intersection. (Possibly many intersections.)

Two curves are inconsistent is it is impossible for any point to be on both. (Being on one curve is inconsistent with being on the other -- it contradicts, being on the other.) There is no intersection.

Statements are consistent if it is possible for both to be true, statements are inconsistent if it is not possible for both to be true. (The truth of one is consistent or inconsistent with the truth of the other.)

  • How many kinds of solutions are there?

    Answer:

    From the category in which this question is asked, I will assume you mean a finite linear system of equations. If such a system is in#n#variables, then there are#n + 2#kinds of solutions.

    Explanation:

    If a linear system involves#n#variables,#x_1, x_2,..x_n#, then the solution set will take one of the following#n + 2#forms:

    (0) The empty set. The system is inconsistent and has no solutions.
    (1) A unique solution in the form of an#n#-tuple
    (2) A line of solutions expressible as:

    #x_1 = a_1*t + b_1#
    #x_2 = a_2*t + b_2#
    ...
    #x_n = a_n*t + b_n#

    for all#t in RR#

    (3) A plane of solutions expressible as:

    #x_1 = a_1*t_1 + b_1*t_2 + c_1#
    #x_2 = a_2*t_1 + b_2*t_2 + c_2#
    ...
    #x_n = a_n*t_1 + b_n*t_2 + c_n#

    for all#(t_1, t_2) in RR xx RR#

    ...
    (n+1) The whole of#RR^n#

  • What are consistent and inconsistent systems?

    A system of equations is said to be consistent if it has at least one solution; otherwise, it is inconsistent.

      How do you determine if a linear system is consistent or inconsistent?

      Definition: A system of linear equations is said to be consistent if it has either one solution or infinitely many solutions. A system of linear equations is said to be inconsistent if it has no solution. system can be recorded compactly in a rectangular array called a matrix.

      How do you know if a system is inconsistency or consistency?

      To see if the pair of linear equations is consistent or inconsistent, we try to gain values for x and y. If both x and y have the same value, the system is consistent. The system becomes inconsistent when there are no x and y values that satisfy both equations.

      How do you know if a linear equation is consistent?

      A system with exactly one solution is called a consistent system. To identify a system as consistent, inconsistent, or dependent, we can graph the two lines on the same graph and see if they intersect, are parallel, or are the same line.

      How do you know if the linear equation is consistent inconsistent and dependent?

      A system of equations is consistent if it has at least one solution. A system is inconsistent if it has no solution. In a system of two equations in two variables, the equations are dependent if one equation is a multiple of the other. Dependent systems have an infinite number of solutions – every point is a solution.
