Question

Choose the correct options for the following questions. 6. If the pair of equations 2x + 3y = 10 and x + ky = 7 has no solution then, what is the value of k? (a) 3 (b) 6 (c) 4 (d) 3/2​

Answer 1

Answer:

2x+3y=10

a1x+b1y+c=0

a1=2

b1=3

c=-10

x+ky=7

a2x+b2y +c2=0

A2=1

b2=k

c2=7

A1/A2=B1\B2

2/1=3/k

2×k=3

k=3/2

d options are true
