Express the system of equationskx + 2y = 02x + 4y = 1in matrix form, where k is a real constant.Hence, find the values of k for which the system has a unique solution.
Express the system of equations
kx + 2y = 0
2x + 4y = 1
We can write this in matrix form as
systen AX=b has unique solution if det(A) is non zero.
Thus system of equation has unique solution for all value of k ,except 1.
