    k  =   8/28k


    k  =   2/7k


    -2/7k  +  7/7k  =  2/7k  -  2/7k


    5/7k  =  0


    5/7 / 5/7  =  0 / 5/7


    k  =  0 x 7/5


    k  =  0











    k=8k/28
    (oh oh...where did this huge type come from)
    you want to get the unknown on one side of the equals sign all by itself.  Do this by performing opposite operations to negate other quantities.  (multiply/divide; add/subtract)
    k=8k/28
    Multiple both sides by 28 to get that 8k by itself. 
    k x 28 = 8k/28 x 28
    28k = 8k
    Your equation doesn't work.
