a/h+a/k=k

(a/h)(k/k) + (a/k)(h/h) = k

(ak/hk) + (ah/hk) = k

(ak + ah) / (hk) = k

ak + ah = k (hk)

ak + ah = h(k^2)

ah - h(k^2) = -ak

h ( a - k^2) = -ak

h = (-ak) / (a - k^2)

h = ak / (k^2 - a)

ak/hk+ah/hk=k
(ak+ah)/hk=k
ak+ah=hkk
ah=hkk-ak
h=(hkk-ak)/a
h=hkk/a-k

(ak+ah)/hk=k
ak+ah=hk^2
hk^2-ah=ak
h(k^2-a)=ak
h=(ak)/(k^2-a)

a / h = k - a/k
a/ h =( k square - a) / k
h = a * k / k square - a
