Question

Find the value of k for which the following system of equations has a no solutions
1.)kx-5y=2,6x+2y=7
2.)2x-ky+3=0,3x+2y-1=0
write complete ans

Answer 1

If the equation has no solution then

a1/ a2 = b1/ b2 = not c1 / c2

here

1) a1 = k ; a2 = 6

b1 = -5 :;b2 = 2

k / -5 = 6/2

k = -15 Ans

2) YOU CAN SOLVE THE ANOTHER IN THE SAME WAY.

Answer 2

This is the complete answer of both questions.
