-4k%2B5%3C21 Start with the given inequality.


-4k%3C21-5 Subtract 5 from both sides.


-4k%3C16 Combine like terms on the right side.


k%3E%2816%29%2F%28-4%29 Divide both sides by -4 to isolate k. note: Remember, the inequality sign flips when we divide both sides by a negative number.


k%3E-4 Reduce.

Answer:

So the solution is k%3E-4

Here's the graph of the solution set on the number line



Note: there's an open circle at the endpoint.
