Question

For what value of k, the pair of equations 4x – 3y = 9, 2x + ky = 11 has no solution?

Answer 1

Answer:

k=-3/2

Step-by-step explanation:

4x-3y=9 ; 2x+ky=11

a1=4 ; a2=2

b1=-3 ; b2=k

c1=-9 ; c2=-11

for pairs of equation with no solutions,

a1/a2=b1/b2≠c1/c2

∵a1/a2=b1/b2, we get

   4/2=-3/k

=>4k=-6

=>2k=-3

=>k=-3/2

Answer 2

Answer:

4/2=-3/k

4k=-6

2k=-3

k=-3/2
