An important and conceptual question from linear equations in two variables in which we have given two equations x+2y=3, 5x+ky+7=0 and we have to solve the equations in such a way that it has a unique solution and also asked to solve the equations in such a way that it has no solution and also asked to find the value of k in such a way that it has infinite solutions.
