Answer:
for no solution condition is a1/ a2 equal to b1 /b2 not equal to c1/c2 and you can find answer accordingly
therefore 2/3 =k/(-5) which implies k = -10/3
also k/(-5 )must not equal to 1/7
and 10/-15 not equal to 1/7

Answer:
Hey,
We have
2x +ky=1..... .. (1)
And 3x-5y=7......(2)
These are in form of general equation
Hence. A1=2,B1=K,C1=-1
AND A2=3,B2=-5,C2=-7
Hence ratio of them are equal
A1/A2=B1/B2
Now
- 5×2=3×k
Then,
K=-10/3
That's your answer
