Question

find the value of k for which of the following system of equations has no solution : x + 2y = 0 , 2x + ky = 5​

Answer 1

Answer:

check if the answer is correct

Answer 2

Answer:

x+2y=0-----------1

2x+ky-5=0----------2

this given system we will have no solution,if

1/2=2/k=|0/-5

now,1/2=2/k=|0/5

k=2×2/1

k=4

hence,proved
