#k=90#

Explanation:

To eliminate the fraction, multiply ALL terms on both sides of the equation by 9, the denominator of the fraction.

#(cancel(9)^1xx-k/cancel(9)^1)+(9xx6)=(9xx-4)#

#rArr-k+54=-36#

subtract 54 from both sides.

#-kcancel(+54)cancel(-54)=-36-54#

#rArr-k=-90rArrk=90" is the solution"#
