WebA system of linear equations usually has a single solution, but sometimes it can have no solution (parallel lines) or infinite solutions (same line). This article reviews all three cases. One solution. A system of linear equations has one solution when the graphs … WebMay 21, 2016 · b)the rank r_2 = r_1 + 1, in this case no solutions for the system. In your example, the determinant of associated matrix is:-7a^2+112. So a) if a is not in {-4,4}, there is existence and uniqueness of the solution. b) If a = 4, then r_1 =_r_2 = 2, there are infinitely many solutions. c) If a = -4 then r_2=r_1+1= 3, there 's no solutions.
