20-x+%3C+k Start with the given inequality

20-x+%3C+0 Plug in k=0


-x%3C0-20Subtract 20 from both sides


-x%3C-20 Combine like terms on the right side


x%3E%28-20%29%2F%28-1%29 Divide both sides by -1 to isolate x (note: Remember, dividing both sides by a negative number flips the inequality sign)



x%3E20 Divide

--------------------------------------------------------------
Answer:
So our answer is x%3E20
