Question

if the system of equation x+2y=5 and 3x+ky+15=0 has no solution then k=​

Answer 1

this equation has no solutions
therefore,
1/3=2/k=-5/-15

therefore,
1/3 = 2/k
k= 6

therefore the value of k is 6

hope it will be understandable and helpful ....

Answer 2

Answer:

k=6

Step-by-step explanation:

x+2y=5

3x+ky+15=0

x+2y=5

3x+ky=15

a1/a2=b1/b2

1/3=2/k

k=6

for any value of k the eq have unique solution except 6
