Q. 15: Let k be a constant. The equations kx + y = 3 and 4x + ky = 4 have a unique solution if and only if
15. C.
Two generic equations, a1x + b1y + c1 = 0 and a2x + b2y + c2 = 0, will have a unique solution if and only if, .
We have the equations kx + y = 3 and 4x + ky = 4,
For them to have unique solutions, they must satisfy the condition
