Answered by Reiny
where did the k come from in line 2 ?
-4k+4k = 0 , so your k's disappear

-38=-4k-8+4k-28
-38 = -36
which is a false statement, so there is no solution

If your variable disappears and you have
- a true statement, there will be an infinite number of solutions
- a false statement, like in your case, there is no solution.
