Question

For which value(s) of k, do the pair of linear equations: kx + y = k2 and x + ky = 1 have a unique solution?​

Answer 1

Step-by-step explanation:

Equation given

kx + y = k^2

and

x + ky = 1

Since the equations have infinitely many

solutions

Thus

Comparing the coefficients of x and y

k/1 +1 or ‐1

k = +1/ root 2 or ‐1/ root 2
