Answer:
Step-by-step explanation
In these type of questions we can use a trick to find answer
let's say we have two linear equation
1) ax+by+c=0
2)mx+ny+t=0
if a/m = b/e ≠ c/f that means we don't have any solution for these two equations ( that's because of analitic geometry)
so,
2x-ky-14=0
5x-2y-5=0
2/5=k/2≠14/5
k=5
