I need an example of a matrix that has no solution. I also need to know how to use row operations to show why the problem has no solution.
Any two parallel lines in the plane that are not the same line, cannot intersect.
For example, the following equations
x + 2y = 1
x + 2y = 3
represent two parallel lines (same slope, different y-intercepts) that do not intersect at ...
This provides an example of a matrix with no solution and how to use row operations to confirm this.
