Answer:

#k>=-4#

Explanation:

You just have to keep in mind that multiplying or dividing both side by a negative number, in inequality, swaps the inequality sign!
Now proceed the problem with usual approach.
We have,

#5-4k<=21#

Subtracting both side by 5 and dividing both side by -4,

#:. k>=-4#
Hence the answer.

Hope it helps :)
