The sum of firstl llAP.for which the pair of linear equations kx + yk2

1.	The sum of firstl llAP.for which the pair of linear equations kx + yk2 and x + ky = 1 haveinfinitely many solutions.
Answer» Equations given kx + y = k^2andx + ky = 1 Since the equations have infinitely many solutionsThuscomparing the coefficients of x and y k/1 = 1/k = 2k/1 thusk = +1 or -1k = +1/ root2 or -1/ root2

The sum of firstl llAP.for which the pair of linear equations kx + yk2 and x + ky = 1 haveinfinitely many solutions.

Answer»

Equations given

kx + y = k^2andx + ky = 1

Since the equations have infinitely many solutionsThuscomparing the coefficients of x and y

k/1 = 1/k = 2k/1

thusk = +1 or -1k = +1/ root2 or -1/ root2
