Question

Find the values of K for. which the system of equations has a unique solution

X - 2y = 3

3x + ky = 1

Answer 1

if a pair of equation have unique solutionthen a1/a2 not equal to b1/b2
so
here
l/3 not equal to -2/k
knot equal to -6
there for all other values except -6 gives unique solution
