well, even I am convinced that the answer was 5. Since both the lines were parallel, their gradient was the same..

It cant be 5 because you have to reduce the equation so u get in the form y=(something)x + y-intercept, only then can u find out the gradient.
So when u divide the whole 5x + 4y =10 and rearrange the equation u get: y= 1.25x+ 2.5
Now 2y-kx=14
U find the value of k it will be 2.5 because to get the equation in the form y=(something)x+y-intercept, the whole equation would be divided by 2, so to get it in the original equation form u need to multiply 1.25 by 2
GREAT, THATS WHAT I WROTE

now i am confused between 2.5 and 5...I do get the idea of rearranging the equation to y=mx+c but i still think 5 maybe the correct answer...though i wont say 2.5 is wrong! so better not to worry over spilt milk and prepare for the upcoming exams.
