Question

The value of K for which the Linear Equation x + 2y=3 and 5x + ky-7 has solution​

Answer 1

Step-by-step explanation:

X+2y=3

5x+Kya=-7

a1=1 b1=2 c1=3

a2=5. b2=k. c2=-7

For unique solution this equation must have

=>a1/a2≠b1/b2

so, by this

1/5≠2/k

10≠k

So, the value of k can be any real no. but not 10.
