Question

find the value of k for which the following pairs of linear equations has no solution.x+ky=2 and 2x-5y=3​

Answer 1

Answer:

-5/2

Step-by-step explanation:

by using condition for no solution

a1/a2 = b1/b2 is not equal to c1/c2

in the above linear equations

a1/a2= 1/2

b1/b2= k/-5

c1/c2=-2/-3 i.e 2/3

so

a1/a2= b1/b2

i.e 1/2=k/-5

k= -5/2 which is not equal to c1/c2 ( 2/3)
