Best ResponseYou've already chosen the best response.0y=18 is the correct answer, not y=10. when you multiply 2 negatives, it will become a positive, making it +14+4=18. For your second question, 5>9+r. Simply subtract 9 from both sides making it 4>r. Then to put it on a number line, just put an open circle on x=4 and indicate that r is everything that is smaller than than 4, so shade the number line to the left for all negative numbers less than 4.
