System of Linear Equations having No Solution

A system of linear equations means two or more linear equations. If these two linear equations intersect, that point of intersection is called the solution to the system of linear equations.
OR
A solution to a linear system is an assignment of numbers to the variables such that all the equations are simultaneously satisfied.
Systems have no solution when the lines have same slope (i.e. Lines are parallel) and the lines have different y-intercepts.

Example: Solve the system of linear equations.
          3x - y = 10
         -6x + 2y = -6
Solution: Given,
          3x - y = 10 ... (i)
        -6x + 2y = -6 ...(ii)
multiplying equation (i) by 2, we get
          6x - 2y = 20 ...(iii)
add the two equations (ii) and (iii)
          0x + 0y = 14 or 0 = 14
As there are no values of x and y for which 0x + 0y = 14, the given system of equations has no solutions. This system is inconsistent.
 
   
As many of you know, Winpossible's online courses use a unique teaching method where an instructor explains the concepts in any given area to you in his/her own voice and handwriting, just like you see your teacher explain things to you on a blackboard in your classroom. All our courses include teacher's instruction, practice questions as well as end-of-lesson quizzes for practice. You can enroll in any of our online courses by clicking here.

The format of Winpossible's online courses is also very suitable for teachers who are using an interactive whiteboard such as Smartboard on Promethean in their classrooms, because the course lessons can be easily displayed on such interactive whiteboards. Volume pricing is available for schools interested in our online courses. For more information, please contact us at educators@winpossible.com.
