Question

H=l/l-2k make k the subject​

Answer 1

`k=(l(h-1))/(2h)`

Explanation:

The given equation is :

`h=(l)/(l-2k)` ....(1)

We need to find the value of k.

Cross multiplying equation (1)

`h(l-2k)=l\\\\hl-2hk=l\\\\hl-l=2hk\\\\k=(l(h-1))/(2h)`

So, the value of k is equal to
`(l(h-1))/(2h)`.
