-5x%2B1%3E11 Start with the given inequality



-5x%3E11-1Subtract 1 from both sides


-5x%3E10 Combine like terms on the right side


x%3C%2810%29%2F%28-5%29 Divide both sides by -5 to isolate x (note: Remember, dividing both sides by a negative number flips the inequality sign)



x%3C-2 Divide

--------------------------------------------------------------
Answer:
So our answer is x%3C-2
