Question

the pair of equation 2x+3y=5 and 6x+ky=12 has no solutions if k=

Answer 1

Answer:

this is the answer . i hope it's helpful

Answer 2

Answer:

k=9

Step-by-step explanation:

2x+3y=5--------------take as eq 1

6x+ky=12--------------take as eq 2

now,

A1=2. A2=6

B1=3. B2=k

c1=5. C2=12

now,

A1/A2=B1/B2 is not equal to C1/C2.

2/6=3/k is not equal to 5/12

so,take,

do cross multiplication. for A1/A2. and B1/B2.

now. after cross multtiiplying ,

2×k=3×6

2K=18

k=18/2

k=9

it is correct

hope it helps you
